Felix received undergraduate degrees in biology (2011) and philosophy (2013) from the University of Munich in Germany, and a Master's degree from Columbia University (2012). Before joining the Hoekstra Lab in 2014, he investigated the molecular basis and evolution of mosquito preference for humans with Leslie Vosshall at Rockefeller University. He also studied the genetic basis of C. elegans aggregation behavior with Mario de Bono at the MRC Laboratory of Molecular Biology in England. Felix is an avid herpetologist, and has worked extensively on the amphibians and reptiles of Cyprus. In the Hoekstra Lab, he is interested in the molecular basis of behavioral evolution in Peromyscus, with a specific focus on innate anti-predator behavior. Felix received Harvard's Herchel Smith Graduate Fellowship and most recently an HHMI International Graduate Fellowship.
