Research interests

My research aims to better understand (1) the relative importance of premating and postmating isolation to the speciation process, and (2) their modulation by the social environment. This work is in collaboration with Mike Ritchie and Nathan Bailey, and I am funded by the Swiss National Science Foundation.

Previously, I did my PhD on a flatworm, aiming to illuminate sexual selection theories with the worms’ fluorescent sperm. This work was conducted under the supervision of Lukas Schärer, at the University of Basel, Switzerland.
