Applying Biostat PhD as MD?

[deep_lazy]

Hello,

I'm an international student studying medicine in a country where med schools are typically undergraudate courses like the UK (2 year premed + 4 year med course).

Currently, I'm planning to study biostatistics (especially focus on statistical/population genetics) in grad school but I have little information about it since very few people (almost none) apply to biostat from my department.

I double majored mathematics at my premed years: GPA around 3.9/4.0, also took some graduate level math courses (graduate real analysis, mathematical algorithms etc), however, the gpa on med courses aren't as good as my math gpa (somewhere around 3.3~3.5 depending on the remaining semesters).

It seems that GPA of 3.3~3.5 isn't really a nice one compared to most applicants applying to biostat.

So my two questions are..

1. Does having an MD helpful when applying to biostat departments?

2. How are GPAs in med schools considered when applying to grad schools?
