Professor David Eilam is a neuroscientist and ethologist, recognized for his pioneering work in the fine-grained analysis of human and animal behavior. Bridging the gap between zoology and psychiatry, his research explores the profound connections between brain and behavioral routines. Professor Eilam is internationally renowned for establishing translational animal models to decode the mechanisms of Obsessive-Compulsive Disorder (OCD). By meticulously mapping spatial locomotion and motor patterns, his laboratory quantifies behavioral repetition, addition, and incompleteness, offering transformative insights into how mental disorders manifest physically and providing a vital framework for understanding the neurobiology of ritualized behavior.
