How to Find PhD Supervisors in Statistics (and Get Funded)

Statistics is its own field with its own professional societies, its own funding agency, and its own department structure, but a lot of outreach advice treats it as a subset of either math or data science. It isn't quite either. Statistics departments are sometimes standalone, sometimes folded into math, and a handful of universities are actively splitting them apart right now. Statistics PhD funding runs mostly through NSF rather than the NIH money that funds biostatistics, and the field has its own arXiv archive with a clean, searchable structure that math as a whole doesn't have. Here's what's actually different about finding and reaching a statistics supervisor, and where the general advice for nearby fields still applies and where it doesn't.

Statistics isn't always its own department, and that changes how you search

Before you can search faculty pages systematically, it helps to know that "statistics department" isn't a single, consistent thing across universities. Some schools run statistics as a fully standalone department, Ohio State and the University of Akron are two examples. Many others run a combined Department of Mathematics and Statistics, with statistics faculty listed under a shared departmental page rather than their own. And the structure isn't static. Both Amherst College and Williams College had their faculties vote in recent years to split their combined math and statistics departments into two independent ones, a change the American Statistical Association's own magazine covered directly, driven partly by statistics and data-related majors growing fast enough that a shared department structure no longer fit either group well. The practical upshot: when you're building a list of target faculty at a specific university, check whether statistics has its own department page before assuming it's buried inside math, and don't be surprised if that answer changes at the same school a year or two from now.

This is a different problem from the one covered in our piece on finding professors in data science with funding, where the issue is that data science is frequently a research area split across several departments at once rather than a department of its own. Statistics is more often an actual department, the question is just which one, and whether it's sharing a page with math or not.

How statistics PhD funding actually works: a department commitment first

Statistics PhD funding follows a pattern close to mathematics rather than a lab science. Graduate program handbooks from Northwestern, the University of Illinois, the University of Georgia, and the University of Rochester all describe the same basic sequence: you're admitted to the department as part of a cohort, you're funded in your early years through a teaching assistantship rather than a specific professor's grant, and you choose, or are matched with, a dissertation advisor only after passing your qualifying exams, typically sometime in your first or second year. At Illinois, for example, every PhD student is required to teach a statistics or math course, or serve as a discussion TA, for at least one or two semesters as part of this funding structure. The department, not an individual faculty member, is the funder during this period, which is also why statistics PhD admission generally doesn't require you to line up a specific professor's agreement beforehand the way a wet-lab PhD does. Our piece on finding PhD supervisors in mathematics walks through the mechanics of this same TA-first, advisor-later model in more depth, since it applies almost identically here.

Where a professor's own NSF grant comes in, and why it still matters

The professor-funded piece shows up later, once you've picked a dissertation advisor after your qualifying exams. At that stage, it's common to move from a department TA line to a research assistantship paid from your advisor's own grant, most often funded through NSF's Division of Mathematical Sciences. DMS runs a dedicated Statistics Program that funds research in statistical theory and methodology, including methods applied to other scientific and engineering domains, and that grant money is frequently what pays for a graduate RA line in a later year of the PhD, on top of whatever TA or fellowship support continues in parallel. This is worth raising directly with a potential advisor once you're choosing one: whether they currently hold an active DMS award, and whether it currently supports an open RA position, since grant cycles run for a fixed period and a professor who was well funded two years ago may not be right now. NSF's own public award search lets you look up any researcher by name and see their current and past funded awards directly, a more reliable check than inferring funding status from a faculty page that may not be kept current.

Biostatistics vs. a "pure" statistics PhD: different housing, different money

If you're researching statistics PhDs, you'll run into biostatistics constantly, and the two are genuinely different programs with different funding mechanics, not just different names for the same thing. A biostatistics PhD is typically housed in a school of public health, focuses on applying statistical methods to biological, clinical, and public health research questions, and draws a large share of its funding from NIH, including institutional T32 training grants and individual F31 fellowships. Both of those NIH mechanisms carry a statutory citizenship requirement, the trainee generally has to be a US citizen, US national, or lawful permanent resident, which the institution can't waive regardless of how strong an applicant is. A "pure" statistics PhD, by contrast, usually sits in a college of arts and sciences, tends to be more theoretical, generally expects real analysis as a prerequisite in a way biostatistics programs don't always require, and draws more of its external funding from NSF rather than NIH. NSF research-grant-funded RA positions don't carry the same citizenship restriction that NIH training grants do, which makes the realistic funding path noticeably different for an international applicant depending on which of the two programs you're actually looking at. Our guide to finding PhD supervisors in public health goes deep on the NIH T32 and F31 citizenship rules specifically, worth reading in full if biostatistics is on your list alongside statistics.

The NSF GRFP covers statistics, but the citizenship rule doesn't change

The National Science Foundation's Graduate Research Fellowship Program groups statistics under its broader Mathematical Sciences field category alongside mathematics itself, so it is a field GRFP explicitly funds. That doesn't change who's eligible to apply, though. GRFP eligibility requires US citizenship, US national status, or permanent residency at the time of application, and that requirement applies the same way regardless of which eligible field you're in. If you're an international applicant, GRFP simply isn't part of your realistic funding picture, and the department TA lines and later advisor-funded NSF DMS research assistantship described above are where your actual funding will come from instead.

ASA and IMS: two different professional societies worth knowing apart

Statistics has two major professional societies, and they're worth telling apart because they serve different purposes. The American Statistical Association describes itself as the field's big tent, with roughly 18,000 members spanning academia, government, and industry, and it runs resources genuinely useful for a prospective PhD student: a compiled directory covering statistics and biostatistics programs across the US, student travel awards for its annual meetings, and named scholarships including the Ellis R. Ott Scholarship, which has offered awards to promising master's and PhD candidates in statistics and related fields. ASA also runs fellowship programs that place graduate researchers at federal agencies, the ASA/NSF/Census Bureau Research Program and the ASA/NSF/BEA Fellowship Program among them, worth knowing about if a government-adjacent research placement interests you during your PhD. The Institute of Mathematical Statistics, by contrast, is smaller, around 4,000 members, grew directly out of ASA in 1935 specifically to support more mathematically rigorous research in statistics and probability, and is the more academically and research-oriented of the two, closely tied to the field's top theoretical journals. If you're aiming at a research career, IMS's membership and meetings are the more directly relevant of the two to track, though there's no reason not to use both as resources while you're building a list of active researchers and programs.

Checking whether a specific professor is currently active and grant-funded

Once you've got names, the most useful statistics-specific tool for confirming someone's currently active is arXiv, and it works cleanly here in a way it doesn't for math as a whole. Statistics became its own top-level arXiv archive in April 2007, having previously existed only as a subcategory inside the Math archive, and it's now organized into clearly labeled subcategories: stat.ME for methodology, stat.AP for applications, stat.ML for machine learning, stat.CO for computation, and stat.TH for theory. Searching a professor's name within stat.ME and stat.AP specifically is a fast way to see what they've actually posted recently, since a lot of current statistical methodology work appears there ahead of formal journal publication. Pair that with a Google Scholar search for their full citation and publication history, since arXiv alone can undercount older or more applied work, and with NSF's public award search to check whether they currently hold an active DMS award at all. None of these three sources alone tells you definitively whether a specific professor has an open, funded RA position for a new student, but together they give you a genuinely informed basis for reaching out, rather than guessing from a faculty bio page that may not have been updated in years.

Why outreach before applying still helps, even in a cohort-funded field

Because early funding runs through the department rather than a single professor's grant, statistics admission doesn't generally require securing an advisor's agreement before you apply, the way it would in a lab science. That makes it tempting to skip outreach entirely. It's still worth doing, though, for a narrower reason: a well-targeted email to a specific professor whose recent stat.ME or stat.AP paper genuinely matches your interests can tell you things an admissions page can't, whether their research area is actually moving the direction you think it is, whether they expect to be taking on new students in the relevant cycle, and whether they currently have an active grant that could support an RA line once you're past your qualifying exams. Treat it as a way to sharpen your program choice and surface genuine fit, not as a funding gate you have to clear before you can apply.

A practical approach

• Check whether your target university runs statistics as its own department or combined with math before building your faculty list, and search both department pages if they're still joined.
• Decide upfront whether you're looking at a biostatistics PhD or a "pure" statistics PhD, since the department housing, prerequisites, and realistic funding source differ meaningfully between the two.
• If you're a US citizen, national, or permanent resident, check current NSF GRFP deadlines, if you're international, plan your funding around department TA lines and a later NSF DMS-funded RA position instead.
• Cross-check a specific professor on arXiv's stat.ME and stat.AP listings, Google Scholar, and NSF's public award search before emailing them, so your outreach references something genuinely current.
• Use outreach before you apply to test fit and ask real questions, not as a precondition for admission, since most funded programs admit at the department level first.

Once you've identified statistics professors whose current, grant-funded research genuinely matches your interests, GradScoutFunding searches professors by field and country, confirms they're actively publishing, and drafts a personalized first email grounded in a real recent paper of theirs for you to review and send yourself, it never sends anything automatically, and it never auto-sends a follow-up either, it drafts the follow-up content and timing for you to review.
