Brian is a PhD student from the University of California Berkeley, visiting the Couzin lab as a DAAD research fellow. He studies the aggressive behaviors of social trematodes (i.e., flatworms, blood flukes), specifically how trematode soldier morphs perceive their enemies, and decide to attack them. Using computer vision, he is testing if soldiers in combat might “recruit” other soldiers into collective defense of their colony. His other work involves colony recognition in ants at the Tsutusi lab in Berkeley, and his primary research interest is to study social evolution in parasites.
