Often you'll have extremely Math-oriented collaborators, but it is useful enough to understand what the hell they're talking about.

Field epi is decidedly non-math. 2x2 tables and odds ratios-- the workhorse methods of the county health department epi-- are not the stuff of math journals. Those bar napkin calculations work. They are typically enough to handle a food borne illness outbreak. You can be a very good epi with very simple tools and a basic understanding of math.

Research is a bit different, but even on the social side where it is so tempting to make elaborate models with heroic assumptions, the best models are extremely simple. The danger is that people try to use tools in new ways without understanding how they work. That is where knowing bio and being strong on the math side makes a difference. It works both ways. Some of the worst errors I've seen were made by mathematicians who were consulting/collaborating but didn't know a damn thing about bio.
