My only authority on the subject matter is that I am currently doing a PhD myself, and in the six years I have spent in the program and the system, and talked to several people in academia, I have learnt a lot, and I wish I knew all this when I started applying to grad schools. My hope is that my experience and understanding will be of good use to aspiring grad students.

This post starts with the following assumptions:

  • You (the aspiring student) have decided to go for a PhD in your respective discipline.
  • You have some idea of what your field of research is going to be
  • Based on your own guidelines you have come up with a list of 15-20 schools that you could potentially apply to.
  • You are looking to narrow this number down to handful/manageable list such that upon being accepted at one of these schools, you will be able to actually do research in the area of your choice and will actually enjoy it.

I am very aware that every discipline is unique in many ways and what applies to one may not apply to another. Given that my ‘expertise’ is in only one field, namely computer science (simply because that is my area of research), this guide  reads more like a fictional case study.

Like I said before, you have a list of schools (in the US) that you might considering applying to for your PhD, but which ones are right for you? For that, first you have to know the kind of faculty you work well with. Here are a few questions you have to ask yourself to be able to determine that:

  1. How narrow/specific is your field of interest? Do you already have your dissertation problem picked out?
    • If are in a very narrow field (with potentially a problem already picked out), then the odds are that there are very few faculty working in this field. Contact them individually and not all at once, until one of them agrees to be your advisor. If no one agrees to it, then pick a different (less narrow) field and read on.
  2. How independent is your work style? Do you work efficiently on your own and need an advisor only if you happen to be “stuck”, or do you need a moderate supervisor with weekly status meetings so that the advisor can ensure that you are on track, or are you a complete flake and need constant supervision and micromanagement to get things done?
    • The answer to this question will determine the kind of advisor who works for you, and by extension you should consider applying to the institutions that employ such faculty members.So if you work well will minimal supervision, then you might want to consider working with tenured faculty members who have a relatively large group of students working for them. The larger the group, the less is the amount of time the faculty member can devote to each student. Often, such groups also have a hierarchical structure with post-doctoral researchers having a great amount of interaction with the primary faculty member, and post-docs mentoring senior graduate students, and senior graduate students mentoring the rest.On the other hand, if you work well with moderate supervision, then consider working with a (preferably) tenured faculty member with a moderate size group.If you think you need constant supervision, but are willing to work hard, then consider working with tenure-track faculty members. Tenure-track faculty members are under a constant pressure to publish (or perish) until they get tenure. So they have a lot at stake if you do not publish, so they will ensure that you will be sufficiently motivated, managed, and worked so as to publish research.
  3. What kind of a research career are you looking for? Would you publish quickly and publish a lot, or would you rather publish at a pace comfortable to you, but publish really high-quality research? Note that the two choices are often in competition (very few like Erdos managed to do both).
    • This goes to the heart of the kind of faculty you should work with. If you are looking for a lot of publications, then look at tenure/tenure-track faculty who publish in the double digits each year (more on how to determine that coming up). Otherwise, look to tenured faculty whose publication list is not 20 pages long, but their work has been cited time and again (more on how to determine this is coming up as well).

Based on the answer to the above questions you should get have an idea of what kind of faculty you want to work with. Now keep that in mind when browsing through the list of faculty at each school on your list.

The next step is look at each school on your list and determine whether or not the school is worth considering for a PhD application. Here is where the process for each discipline varies. I will proceed ahead like this is a (fictional) case study for the discipline of Computer Science. Say, the field of research interest is Theoretical Computer Science, and the school I am looking at is Massachusetts Institute of Technology (MIT). Note that you will have to repeat the following process for each school on that list.

First, open up with department website to get to the list of faculty who are working in your field of research interest. In the specific example of Theoretical Computer Science at MIT, it is http://theory.csail.mit.edu/people.html. Note that in some (smaller) schools/departments they simply have a list of faculty for the entire department and you will have to scour through the research interests of each faulty member before you can figure out what is you pool of potential advisors.

Now begins the painful task of actually, reviewing each individual faculty member to see whether or not they are the right one for you. First, separate the list of faculty into tenure-track faculty and tenured faculty. Typically, assistant professors are tenure-track faculty, and associate professors and professors are tenured faculty. Go to the personal website for each faculty and see if you can find information on the following:

  1. The list of students currently in their research group
  2. The list of publications from the past five years (don’t go beyond five; faculty research interests tend to migrate). If you cannot find their list of publications on their website then look for this information in other publication aggregation and indexing  sites (like DBLP for publications in Computer Science and Engineering). For instance, the list of publications by Prof. Rivest (of the RSA fame) is http://www.informatik.uni-trier.de/~ley/db/indices/a-tree/r/Rivest:Ronald_L=.html
    In order to determine if the research that the faculty does is of high quality, an imperfect test is to figure out how much their work is cited. On way to do it is to see the venues (journals) where the faculty has published, and what the impact factor of that journal is. For instance, Prof. Rivest’s paper “Translucent Cryptography—An Alternative to Key Escrow, and Its Implementation via Fractional Oblivious Transfer” is published in the Journal of Cryptography whose impact factor (According to http://citeseer.ist.psu.edu/impact.html) is 1.97 (top 3.03%). This suggests that the his work is of greater impact than most.

Depending on the answers to the questions asked earlier and the information gained from the faculty website and the internet, shrink the faculty pool to the list of 3 or so faculty that you would consider to be your advisor.

Now repeat this process for each university on your list and then sort your list based the number of eligible faculty per school and the ranking of the school/program itself (The ranking can be obtained from either the department website, wikipedia, or an internet search).

Now divide the list into three categories: top 1/3rd, middle 1/3rd, and bottom 1/3rd in the sorted list. Apply to at least one school in each category to maximize your chances of an acceptance.

I hope this helps some in making the rather opaque job to selecting a school for your PhD easier.
