I am primarily a theoretician, but one who loves the outdoors. In combination it is a good life: one can visit a field site once someone else (a student, or a collaborator) has already dealt with all the boring logistics, knows the most enjoyable things to do, and has already some exciting data points to show. I call this professional parasitism, but at least some of my collaborators claim to categorize it as mutualism. I hope it's true. As a consequence, some people in my lab have been empiricists who'd like to learn how to build mathematical models of evolutionary processes, others are on the theoretical side themselves, others still are more into ecology than evolution, and so on. What is nice is that they all talk to each other - I believe the fancy word for that is synergy. Read more on my website.
