Stats/Biostat PhD Profile assessments & program suggestion

[c6beyth]

Hi everyone, this is my first time posting on GradCafe. I’ve been reading a lot of profiles here and finally decided to ask for honest opinions.

I am an international student, currently in the US. I finished my Master’s in Applied Statistics and am planning to apply for Statistics / Biostatistics PhD programs for Fall 2027. Although I have pretty solid research experience and publications from my recent job, my biggest concern is my low undergraduate GPA, especially since I want to move toward more methodological work rather than applied research.

Here is my rough profile:

Type: International, currently residing in the US

Undergraduate: B.S. in Statistics (regional public university)

GPA: 3.3 / 4.0

Graduate: M.S. in Applied Statistics (Top ~20 Statistics program)

GPA: 3.7 / 4.0

GRE: Not taken yet

Research Experience:

• Working as a RA at a major medical school research center (full-time 1.5 years)
  • First author in a journal (published, IF 10)
  • co-author in a top-tier journal

Courses:

• Undergrad
  • Math: Calculus 1 (B-), Calculus 2 (A), Calculus 3 (A), Discrete math (B), Linear algebra (B+)
  • Stat: Intro prob (A), Statistical Analysis (A-), Regression (A), Prob models (B+), Prob (A-)
• Master's
  • Intro prob (B), Applied stat (A-), Regression (A), Experimental design (A), Analysis of discrete data (B+), Time series (B-), Intro math statistics (A), Data mining (A) and statistical consulting courses (both A)

My Primary Concerns:

Undergrad GPA: It’s significantly lower than the average for top programs. Does a Master’s GPA and 1.5 years of professional research at a top med school compensate for this?

Transition to Methodology: My publications are in applied journals. I want to pivot to Bayesian & Causal Inference methodology (I used those methods in my pubs but they were applied as existing tools). 

Questions:

1. Realistically, how do you evaluate my chances for Biostatistics PhD at University of Minnesota (Twin Cities) and other similar-level programs (top 20–40 range in Statistics/Biostatistics)?

2. Any advice on how to strengthen my profile further? (should I take GRE? Any specific coursework I should consider before applying? How to best address the undergrad GPA in the SOP?)

I would really appreciate any honest feedback. Thank you in advance!
