Assistant Professor 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 evolution and genetics of social behaviours in insects and other animals. He studies the behaviour, evolution, genetics and genomics of a group of Southeast Asian insects, stalk-eyed flies, in both the field and laboratory. He has also studied the evolution of cooperation and eusociality in a in termites. Along the way he has studied everything from courtship and mating behaviour of mantises, to aggression and territoriality in spiders, to courtship in scorpions, to the songs of some very noisy crickets. He and his students study the social behaviours of Singapore’s urban carnivore, smooth-coated otters. He is especially interested in employing community science to conduct animal behaviour studies.
