Dr Philip Johns earned his BA from Carleton College and his MSc and PhD from the University of Chicago. Before coming to Yale-NUS College, he was a Research Fellow at the University of Maryland, and he taught in various capacities at Villanova University, Swarthmore College, Bard College, and University of California, Los Angeles (UCLA).

Dr Johns’ research interests revolve around the evolutionary genetics of social behaviors in insects and other arthropods. His primary research is on sexual selection and selfish genes in stalk-eyed flies. He also studies the evolution of altruism in termites, and courtship behaviour and aggression in spiders and praying mantids.
