Hee, I'm much more of a micro than a macrobiologist, myself - I'm interested up to the organismal level, but once we start getting to populations I usually tune out. I just find all the trillions of tiny Rube Goldberg machines that have to function perfectly every single time they work for us to even be viable as beings...so much more fascinating. I don't know why.

But I should stop now, before I witter all day at you about genetics. :) I appreciate ecology in a sort of objective way even if it's not my thing as much, and hopefully this professor's enthusiasm will catch a bit.
