Go to grad school with your eyes open!


Stipends in grad school are.... modest (see above) and don't allow the kind of lifestyle that you can maintain with a "real" job. You're still a trainee in grad school, hence all of the comics pertaining to eating ramen noodles and the obsession with free food in PhD Comics, and other blogs about grad school... (and if you didn't think you could live on this kind of stipend [barring personal or family emergencies], why did you sign up for this?)

This past week, the Professor Is In blog began a survey of PhD debt to assess whether reports she'd heard about credit card and loan debt in the 100s of thousands of dollars could be real (i.e., >$260,000 in debt for a philosophy degree). Slate Magazine, The Atlantic, and The Chronicle of Higher Education all have articles about this survey too. You can go to the results of this survey through the above link, but here's a 2012 summary from a similar NSF survey:


Over 60% of the respondents reported zero debt, but nearly a quarter reported debt over $30,000. You can enter numbers for your own grad school experience at the Professor Is In blog. Post-grad school debt is much less of a problem for students in the physical sciences and engineering probably because most of those students are offered both a stipend and full tuition when they're admitted, and because those students spend only ~5 years on average in grad school.


As an undergraduate, I went to a local state university and my parents paid for my tuition. As a graduate student at a big research university, I was single and childless, drove a 15-year-old car, shared an apartment in a less expensive neighborhood that was a bit of a drive from campus, ate a lot of pasta, and didn't eat out much. I had a teaching assistantship for $12,000 (for 9 months) and my tuition was covered by the university. I graduated with $0 debt and had a blast in grad school (and I never took a loan, never had any credit card debt, and never worked another job apart from being a grad student). So zero debt is absolutely possible.... you just have to live like a student.


I really don't understand students that complain about being broke yet buy lunch out daily, drink Perrier instead of drinking out of the free water cooler that the department keeps, buy organic berries from Whole Foods (aka "whole paycheck"), get regular facials, or drive a new car. These examples are based on real people and they are what I consider pretty outrageous choices for someone in school.  If you're in grad school in the physical sciences and you're accumulating serious debt, you're making some seriously poor lifestyle choices, or you made some bad decisions en route to grad school (perhaps a you got a philosophy/religion/english degree at an expensive, small liberal arts college back east and piled up debt?). As a grad student, you're still a trainee (you don't have a degree yet!) and can't expect the same standard of living that your roommate(s) who got a job at Google straight out of college might have. But consider, your roommates may make a whole lot more than a typical grad student, but they have regular work hours, might have a dress code, get only two weeks of vacation per year (and can't leave for an awesome backpacking trip to Chile for 3 weeks at the drop of a hat [without getting fired]), and have to regularly meet deadlines (with complete, quality work...gasp!).

If you're thinking about grad school, go read the "Why did you take out the loans" comments in the PhD debt survey, think about what living like a grad student means, and consider if grad school is right for you before diving in...

The GRE (with a 2020 update)

GRE scores are required with most applications to graduate school. You must (MUST!) study for the GRE because you can improve your quantitative score dramatically even if your math skills are good (even very good), and the quantitative scores are what science faculty look at first. And despite the GRE's shortcomings, the majority of faculty looking at graduate applications give the scores A LOT of weight. The verbal scores are frankly less important (to me and some other faculty, even at large research universities) because it better reflects an applicant's economic background (and, of course, whether an applicant is a native English speaker), and tells us nothing about your ability to write. If I want to know if an applicant can write (and if they're savvy), I look to their e-mails to me and to their statement of purpose.

October 2020 update: There is no statistical correlation between GRE scores and success in graduate school. According to this article in The Atlantic, student performance on the GRE correlates more closely to a combination of factors that includes access to expensive test prep courses and other educational opportunities that prepare students for the test, and even the "student’s own insecurities regarding race and gender." A UCSF study showed that success in graduate school is better predicted by letters of recommendation from faculty advisors who know the student well, and the amount of research experience the applicant already has under their belt.

The Earth & Climate Sciences Department at SF State has joined the growing ranks of geology/Earth science departments that have ended the practice of requiring GRE scores be submitted with grad school applications. Many universities have ended this requirement; some make reporting your GRE scores optional which makes the choice of whether or not to report your scores a new kind of problem (I advise against it unless your scores are top tier). It is not yet universal, but the number of programs adopting this new policy is growing particularly following the impacts of the Covid-19 pandemic. Of course, letters of recommendation aren't a perfect means of evaluation. A 2016 study in Nature Geoscience showed that women are "significantly less likely to receive excellent recommendation letters than their male counterparts" and the length of letters written for women are much shorter.

There is no easy fix here. Faculty in the Earth & Climate Sciences Department at SF State have started to use evaluation rubrics for hiring new faculty to avoid implicit bias. I think it's time to start using a similar rubric to evaluate graduate program applicants... and without a column for GRE scores!

The Statement of Purpose

Graduate program applications generally require you submit a generic application form of some sort, your university transcript(s), GRE scores*, a CV, letters of reference (these should go directly from the letter writer to the university), and a statement of purpose. The SOP is important both for its content and for how well you express yourself.

In general, your statement of purpose (SOP) is a 1-2 page typed description that addresses three areas: (1) Your educational experiences and how they have led to your interest in graduate study in the geological sciences; (2) a description of any scientific research you have conducted (be specific and include field experience, lab/analytical work, a summary of your findings); and (3) a description of your research interests for graduate school and your career goals. A well-crafted statement of purpose is specific about what you want to study and the geology faculty member(s) you are interested in working with. Do your research about the faculty and department to which you are applying and tailor each of your SOPs to that faculty member/department. You do not need to know exactly which one faculty member you want to work with - it's OK to include two or three names (maximum) if they are working in related/complementary fields (but don't include, for example, a geophysicist, a geomorphologist, and a hydrologist - that would demonstrate that you have no idea what you want...). Nor do you need to know exactly which project you want to work on - be as specific as possible about your interests ("extensional terranes", "metamorphic core complexes", "ultrahigh-pressure metamorphism") and certainly include a description of how your research experience has prepared you to tackle your proposed research. Look through the websites of potential graduate advisors to see which projects are active. You can also search the National Science Foundation website to look for active research grants for those prospective advisors (although not all research funding comes through the NSF, that is a major source of funding in the Earth sciences).

This web site and this link have good descriptions of the basics of the SOP (even though these are intended for graduate programs in psychology) and some things to avoid. Whatever you do, don't start your SOP off with the all-too-common "I have loved geology since I was just a kid starting out with my first rock collection" sort of statement. Gag me. Just start with your college experience, or perhaps one notable trip you took where you learned about geology. Be matter of fact, as specific as possible, concise, and use the SOP as a place to elaborate on things only briefly included in your CV (like your research experience) or to discuss things that don't appear elsewhere in your application and that are relevant to your application (e.g., if you need to explain poor GRE scores or a D in a chemistry class in your freshman year). Stay positive and don't make excuses.

Spell check, proofread, and have someone else read your statement and give you feedback before submitting it (a grad student, a faculty advisor, swap SOPs with other students). The rest of your academic record can't be changed at this stage, and you can't control what your letter writers say, but you CAN write an excellent SOP.

*GRE scores are no longer required to apply to the MS program in Geosciences at SF State.

The CV

You need a basic CV as you progress through your career as a scientist: to apply for fellowships and grants, graduate school, internships, etc. Read through this thorough description of a basic science CV by Richard Reis in The Chronicle of Higher Education and see several resources on How to Craft a Winning Résumé on the Science Careers (AAAS) web site. Once you have all your basic info down, you should take particular care to 1) proofread your CV for typos, 2) make sure it is formatted simply so that it is easy to find critical information (e.g., year(s) of your degree(s)), 3) avoid excessive wordiness (less is more - don't use complete sentences to describe your skills, instead use bullets), and 4) keep it to a maximum of 1 or 2 pages unless you already have a PhD and can justify a longer CV (i.e., have you used an 11 pt. font, played with the page margins and spacing? Have you already removed all items related to your high school record? hobbies? and anything else that isn't DIRECTLY related to your career as a scientist?). In early versions of your CV, err on the side of INCLUDING small awards or presentations (a scholarship from the local gem and mineral society, a poster competition in your College of Science, etc.). Include other languages you speak, specialized lab techniques you have experience with, specialized software you use (no, we don't want to see that you've mastered MS Word).

Things that SHOULD NOT be included in your CV: a photo of yourself, your birth date or age, your marital status, an exhaustive list of your college courses, your hobbies (unless you happen to have an Olympic medal or some other very notable "hobby" that will make your CV stand out but perhaps work that into your Honors and Awards section).

Finally, look at CVs of other academics for formatting ideas and ideas for what to include in your CV. I happen to like the way my CV is formatted (I don't overuse bullets, but instead use more bold type, italics, underlining, and creative spacing to make the information easy to find. You should include the dollar amounts of any awards/scholarships in your CV). Then have someone (an advisor or graduate student) look at your draft CV before you send it off. Send your CV as a .pdf file and not an MS Word file to avoid software problems.

Before you submit an application for a PhD program....

After you take the GRE* and after you've chosen a few graduate programs to apply to (see my previous posts here and here), you should take a few steps to make the initial contact with potential future graduate advisors. First, do your research about the faculty member online and maybe read a recent paper or two of theirs. Then draft a professional e-mail to introduce yourself and enquire whether a faculty member anticipates taking any new graduate students for the next academic year. A generic e-mail (from your university e-mail account) might read like this: Dear Prof. X, My name is Jane Doe and I will complete my B.S. in Geology at San Francisco State University in May 2011. I hope to begin PhD research next fall and I am very interested in your research on Interesting Topic Y that I read about in your X et al. (2010) paper in Important Journal of Research. I completed a research project on A and B with Prof. Z at SF State and believe I am well-prepared to start research on Interesting Topic Y at Prestigious University. Do you anticipate taking any new PhD students next fall? I would like to discuss any opportunities you might have to join your research group. I see that you have a poster with Unknown Person [the first author on the poster that you're referring to] on Wednesday morning of the AGU meeting in San Francisco - if you plan to be at the poster that Wednesday morning, may we schedule a time to meet briefly? I am attaching my CV for your reference. Many thanks for your consideration. Best Regards, Humble Student Because the process of applying to graduate programs starts in the fall term, you have two opportunities to make further contact with potential graduate advisors (particularly if their university is too distant to justify a road trip for a casual visit): at the Annual Meeting of the Geological Society of America meeting (in October or November) and the Fall Meeting of the American Geophysical Union (in December). For my students who always attend the AGU meeting in San Francisco, I recommend checking to see if the faculty member is presenting a talk or poster at which you might introduce yourself, hear about their research, and ask intelligent questions: Search the Fall Meeting program for their last name. If you get zero search results back, you can still ask whether they will be at the AGU meeting in San Francisco, and might be able to meet - they might be planning on being a "conference tourist" (i.e., attending but not presenting) or, if not, you get bonus points by showing that you will attend that meeting. You should certainly invite a potential advisor to visit your poster if you're presenting one - be sure to include the details of your poster (i.e., T32E-47) and when you plan to be at your poster (your poster stays up all day, but you will only likely be present for 2-4 hours). If you are an M.S. student writing this e-mail, you should include a few more details about your interest in the faculty member's research and certainly more details about your research experience (tailor it to the specific faculty member: field work, lab/analytical techniques, a one-liner about the preliminary results of your research). Then proofread your e-mail: Fix typos, check the spelling of the faculty member's name, etc. I would add a "signature" at the bottom of your e-mail that has your name and contact information (kind of like a business card): Jane Doe M.S. Candidate Department of Geosciences San Francisco State University 1600 Holloway Avenue San Francisco, CA 94132 Tel: 415-555-5555 (cell phone is OK) Fax: 415-555-5556 E-mail: jdoe@sfsu.edu Home page: http://online.sfsu.edu/~jdoe If you are going to send several of these e-mails, MAKE ABSOLUTELY SURE that you have used the correct name of the faculty member, the correct topic of their research that interests you, and the correct name of their university before clicking 'Send'. It's very easy to change the Dear Prof. X part, and forget to make similar changes to the body of the e-mail. Don't embarass yourself. Then, depending on the response you get, you plan your meeting with him/her at AGU (dress nicely [smart casual, no tie needed], bring a copy of your CV, read the abstract of their poster/talk in advance, etc.), or you reply "Thank you very much! I plan to submit my application to Prestigious University in the next few weeks. Regards, Humble Student". If they say 'no thanks', still take the time to thank them for their response. Whatever you write back, don't just reply "thx", but format your e-mail professionally similar to the first. The whole point of this is to introduce yourself to a potential future PhD advisor so that your application stands out from the rest (or so that you don't waste time and money applying) and so that they remember communicating with you, or meeting you, in a positive light.

Choosing a PhD advisor

A recent blog thread prompted me to read an article by Bruce Alberts, Editor-in-Chief of Science "On Becoming a Scientist" and post some thought on choosing a PhD advisor here.

He starts: “The exact project pursued for a Ph.D. degree is not nearly as important as finding the best place for learning how to push forward the frontier of knowledge as an independent investigator.” How true. Some advice summarized from the article:

1) Choose a research group led by a person with high scientific and ethical standards. Have they published frequently and in prestigious journals? Do they have NSF-supported research projects? Search for their name on the NSF awards web site;

2) Find an advisor who will pay close attention to your development as a scientist (a small research group is perhaps better than a large group in which your interests can get lost). Talk to current students in that group and discover whether they have had conversations with their advisor about their future career. Have they been encouraged to present their research at conferences, write papers and grant proposals? Are there multiple faculty doing research in related fields? That could create a supportive community of faculty and grad students in which you might thrive. Are there regular departmental seminars on topics of interest to you by visiting scientists? Does the research group meet regularly to discuss research progress, etc.? The upshot: is there a community that will provide an intellectually-stimulating and supportive environment?;

3) Choose an advisor that will provide you with enough guidance to prevent you from wasting time on nonproductive pursuits, while giving you the freedom to innovate and learn from your own mistakes. How hands-on or hands-off is s/he as an advisor? Is there a chance that you might become enslaved as the mass spec repair dude during your PhD or will you get lots of hands-on experience in the lab while you're doing your research and walk away 5 years later with important skills;

4) Choose your research project well (this is a tricky one as it's hard to see the forest for the trees when you're fresh out of your undergraduate studies): “ambitious enough to be important and exciting, innovative enough to make unique contributions likely, and nevertheless have a good chance of producing valuable results”. Have this conversation with your advisor when you're choosing your project.

5) The choice of a postdoctoral research group is the place to establish yourself with your long-term career in mind – you should choose a lab where you can acquire skills that complement those you already have.

6) Finally, I'll add that you should consider whether the faculty member is near retirement or whether they are just starting to grow their research program (what year did they get their PhD and do some math) - are they actively doing exciting research? have they published recently? do they have active grants through NSF? Some mid- or late-career faculty might drift into administrative roles that take them away from their research. Very new/young faculty might be sinking all of their time into starting up a new lab or teaching brand new courses and not have much time for advising, they might not have external grant funding yet to support their research, or their research groups might be nonexistent or very small (perhaps not the most supportive environment). At the same time, very new/young faculty might feel more energized by their research and still have a fire in their belly that could lead you down exciting research roads (at the very least, if they are pre-tenure [Assistant Professors in their first 6 years of their positions] they will still have to work very hard to be productive...).

There is an awful lot of luck, knowing the right people, and being in the right place at the right time in becoming a successful scientist. You can control who you know - your research mentors. Choose well.

Applying to PhD programs, part I

Thinking about applying to a PhD program? There is more to consider than just the interesting research being done at a given university. A successful PhD requires:

1) A great research problem - you're going to be working on and thinking about this research for (probably) 5 years. Do your research online and see which universities have geology departments with faculty doing research in your field of interest...is it one faculty member or several? do they have laboratory/analytical facilities to carry out some of this research?;

2) A graduate advisor you can work with for 5 years - are your expectations for how hands-on or hands-off you want your research advisor to be in line with their advising style? Do your personalities mesh? Talk to a potential advisor's students to get a better understanding...;

3) A place you'd like to live. This goes beyond just geography - yes, it does matter whether the university is in an urban or rural setting, on the east or west coast, or whether it's hot and muggy in the summer or covered in snow in the winter (which do you prefer?), but consider the culture in the department you're applying to (is there a big group of students working on similar problems to yours that you might be able to look to for support? do you like them? are people in the department friendly? are doors wide open in the hallways? are there frequent seminars with interesting outside speakers?);

4) Money. No not just the stipend you're likely to be offered. Money to actually get the research done. You can live on Ramen noodles, but you can't get field work and lab work done without research funding. You can ask a potential advisor about this if you are invited to visit campus, but you can also do a little homework to find out if the advisor has any active grants with the National Science Foundation or at least whether they have a history of grant funding.

Don't get your mind set on one or two grad schools you think you'd like...do some searching on the web to see which universities have faculty working on projects that interest you and try to keep an open mind - A big name university might not be the best fit for you (and no, I'm not suggesting you couldn't get in...).

Look for Part II when I'll give advice on how to approach a potential graduate advisor with things to do before, during, and after actually sending in your application.

Also, continue to consider whether graduate school is right for you - research requires a very different set of skills than taking college courses and it's not a good fit for everyone...

Writing a professional e-mail

The subject of how to write an e-mail to a professor or other senior scientist came up in our research group today. I'd like to add my two cents to some resources I found online here, here, and here (that you should spend five minutes to read). While the suggestions on these two websites are most relevant for students in a large enrollment general education course, many of the same pieces of advice should be followed when you want to contact a scientist at another university or lab. Basically, a professional e-mail should be treated more like a formal letter and not a text message to your BFF. And make sure you avoid common pitfalls (that will annoy the very person you're trying to impress).

1) First, can your question be answered by information available on their website (or on iLearn), elsewhere on the web, or by simply looking at their schedule posted outside their office door? Even senior students and grad students still ask me questions they can answer themselves. A good example from two weeks ago: A geology major graduating this semester who missed class to attend an optional geology field trip not related to any course he was taking asked "Did we miss the X lab while we were on the X field trip?". My response: "I don't know. Did you check iLearn?". I spend a lot of time maintaining course web sites to make things more convenient for both me and students. Use those resources.

2) Always (always) address the e-mail to "Dr. X" or "Prof. X". And don't forget to identify yourself: "My name is John Smith and I'm a graduate student working with Prof. Jane Doe at State University". Likewise, close your e-mail "Regards" or "Best Regards" and not "Thanks!" or nothing at all. Include a sensible subject line and keep the e-mail short, but provide enough information so that a response is easy. Don't write "May I have a copy of your 2008 paper?", write "May I have a copy of your Johnson et al. (2008) paper that appeared in the Journal of Important Scientific Discoveries"? Consider whether their response requires knowing more about the context of your question - what kinds of rocks are you working on? where did you collect your rocks? etc. It also can't hurt to start off with a compliment: "I very much enjoyed your recent paper in EPSL. May I ask a question about your EBSD results?".

3) It's always best to use your university e-mail account to send these kinds of e-mails. That makes it very clear you're actually a student at that university and not spam or some random wacko.

4) Get a professional e-mail address. "sillybear714@sfsu.edu" or "toadjuice@gmail.com" should be reserved for personal e-mail communication (if you must). Ideally, grab a firstname.lastname@univeristy.edu account, or (if it's too late for that) a firstname.lastname@gmail.com account.

5) Punctuate, capitalize appropriately, check your spelling, and write in complete sentences. A no-brainer really.

6) If you get a response to your e-mail, you need to take time to say "Thanks!". It's annoying to spend the time to answer questions, etc. and just have it disappear into the ether.

And if you're not sure how to write a tricky e-mail, run it past your advisor first... Particularly if there might be intellectual property issues with your e-mail or if there is any chance you might step on someone's research toes. Not sure? Ask your advisor.

Letters of recommendation

Sooner or later, you're going to need a letter of recommendation from professors/employers who know you and are able to write positive things about you. These kinds of letters are necessary for scholarship/grant applications, applications to graduate school, etc. I often get requests at the last minute, with minimal information about the program for which I'm writing the letter, and without copies of any of the other information the student will submit alongside my letter. I suspect the main reason for the lack of information is procrastination...waiting too long to get around to putting the application together.

If the professor agrees to write the letter, all of this means that they won't have enough information about you to write a thoughtful letter that points to your strengths nor time to think about what they might write. The result? A generic letter of recommendation: "John X. took my Petrology class in Spring 2008 and received a final grade of B+, scoring in the top third of students in that class...He is a hard-worker, turned in all assignments, and asks lots of questions in class....I recommend him for XYZ scholarship." Trust me - that's not the kind of letter you want.

It's best if professors are able to talk about improvement of your grades over time and point to the 3.6 GPA in your geology courses (versus the 3.3 overall GPA) - information contained in your transcript. A resume that includes previous relevant work or research experience, published abstracts, scholarships awarded, community service experience, teaching experience, etc. would provide additional details that might significantly improve a letter of recommendation. Finally, having final (or semi-final) copies of the essay(s), budget, and/or statement of purpose can make all the difference; those documents discuss your qualifications for the grant or what you plan do as part of your graduate research, your motivation for pursuing graduate school, whether they feel you're a good fit for the program/advisor to which you're applying....key elements to a letter of recommendation. If you've chosen faculty who know you well academically, they can discuss whether you're a capable researcher and prepared for graduate school, include details of the kind of research you did, discuss how involved intellectually you were with the project, etc. It is also very important to give your letter-writers copies of any details of the grant/scholarship that you're applying for: who is the funder? what sorts of research do they support? what are the eligibility requirements? do they have a preference to support a particular group (women, minorities, petroleum geologists)? what is the typical grant size? For example, here is some of the text describing GSA's Graduate Student Research Grant program:

"The primary role of the GSA research grants program is to provide partial support of master's and doctoral thesis research in the geological sciences for graduate students enrolled in universities in the United States, Canada, Mexico and Central America. In 2008, 53% of the applicants received funding. GSA strongly encourages women, minorities, and persons with disabilities to participate fully in this grants program."

From this, I can see that they want to partially fund thesis research. That's an important thing to know from the letter-writer's (and the applicant's) standpoint: in a letter, I can emphasize other funding that's available to support a student's research or point to other aspects of the thesis project for which no funding from GSA is requested.

Here is another example from AAPG's Grants-in-Aid program describing how AAPG will choose grant awardees: "Factors weighed in selecting successful applicants include: the qualifications of an applicant as indicated by past performance; originality and imagination of the proposed project; support of the department in which the work is being done; and perceived significance of the project to petroleum, energy minerals and related environmental geology."

Grant proposals often have word/character/page limits that mean you can't necessarily say everything you want in your proposal. Armed with the above information from AAPG's web site, a letter-writer can again better justify funding your proposal by highlighting those specific points about you or your project.

Giving your letter writers all that information with plenty of time (at least 2 weeks before the deadline) gives us good fodder for the letter and puts us in a good frame of mind while we're writing those letters. There is perhaps less need to ask for a letter so formally (see the link above) after the first request, and particularly from your main advisor who has written (multiple) letters for you in the past, but the need for copies of the meat of your application (the essays and budget, the statement of purpose, and program requirements) still stands. Always.

Final tip: academics tend to write more glowing letters than employers/supervisors outside academia (think: the geotechnical firm you worked for right after college) because we know what the competition is like and what stands out (the good and bad) when evaluating a grad school or grant application.

How NOT to impress a future advisor/employer

I often get e-mails that are not well crafted or written with care. The result is that 1) I am annoyed (and I remember which individuals have annoyed me in the past) and 2) I have to waste my time to seek additional information that should have been included in the original e-mail. For example, I just received this e-mail:

Hello Mary,

I am currently applying to enter the MS in Geosciences program (starting in the Fall 2009 semester). Last week I met with [an advisor in your department], and she suggested that I set up a meeting with you to discuss the program as well as potential research opportunities. If you are available to meet sometime in the next week or two, please let me know a day and time. If you are really busy right now, but are able to speak briefly over the phone, you can reach me at 415-xxx-xxxx.

Thank you,

[Potential graduate student]

At least he said "Thank you".

What's wrong with this e-mail? First, he starts by using my first name. I'm perfectly happy with students calling me by my first name but that is perhaps unique to geology (the culture is very different in other fields: for example, all students in the Chemistry Department address their professors with "Dr.", even to their principal advisor). Always
(always) default to addressing someone in academia as "Dr." or "Prof." until you are either requested to do otherwise, or you get some other indication that you may comfortably use a person's first name (how do they sign their e-mails?).

Next delightful shortcoming of this e-mail: This potential grad student didn't bother to tell me anything (anything) about their background or research interests, and gave me no indication he'd even bothered to look at my web site to see what my research interests are. For such a wired generation, students fail an impressive number of times to even search Google (or check their syllabus or the course web site) before sending me an e-mail or coming to my office for information.

Then he goes on to request a meeting without telling me when he might be available, and instructs me that "If you are really busy right now" to telephone him.

I am always really busy.

What I wrote back was this:

Hi [Potential graduate student],

Why don't you tell me a bit about your background? Do you have a B.S. in geology? Do you have any research experience in the lab or field? Did you take a traditional 4-6 week field camp? What are your research interests? What is your ultimate career goal once you have an M.S.?

Thanks,
Mary

I'm really not in a hurry to meet with this guy....but you never know....so that's why I even bothered to reply.
