I am an evolutionary biologist and work on the evolution of drug resistance in HIV. I want to understand what determines the rate of evolution of drug resistance, so that we can find ways to halt the evolution of drug resistance.

Before switching to HIV, I worked on ants, sympatric speciation and soft sweeps. I also write and tweet and make video’s.

If you have questions or would like to discuss an idea, feel free to drop me a line (pennings at!

One Response to “Bio”

    I agree that some of those comments seem to be sexist. Having a foreign PhD also makes things tough. But I don’t think the comments about contribution are neccessarily sexist. I have written similar comments about men, myself. People do look for first author papers and in fields like economics single author papers. People do look for evidence of collaboration with people other than the advisor. Now I just looked at your track record on Scopus and I see there are three papers on “soft sweeps” and two have your name first, though the first and most cited has your advisor’s name first, which is unfortunate. I think this reviewer just looked at that and didn’t notice that the other two parts have your name first and came to the wrong conclusion. So that is bad.
