Excellent numbers to be competitive for a PhD program. But, two big things against you: an MPH is a broad terminal degree and generally offers candidates little room for active research, or even research methods courses, which PhD programs require.
Except very little of that is important to top PhD programs, all of which are funded btw.
And this is the key missing ingredient. If I were you, I’d look to get a job as a research assistant or Lab manager at a top Uni where you can get a couple of years of research under your belt. Then, with your numbers and background, you’d be an extremely competitive candidate to the top PhD programs. (but then, we’ve had this discussion before.)
