I'm an evolutionary computational biologist at Michigan State University. I do modeling and simulations of evolutionary processes (selection, genetic drift, adaptation, speciation), and am the admin of Carnival of Evolution. I also occasionally debate creationists and blog about that and other things at Pleiotropy. You can find out more about my research here.
Update: Wow, that was crazy! 8 hours straight of answering questions. Now I need to go eat. Sorry I didn't get to all questions. If there's interest, I could do this again another time....
Update 2: I've posted a FAQ on my blog. I'll continue to answer new questions here once in a while.
