Julian Meeks started his path towards neurobiology as an undergraduate studying biomedical engineering (B.S. in BME, Saint Louis University, 2001). His interests turned to neurophysiology following an influential summer internship in the laboratory of Jeffrey Diamond, Ph.D. at the National Institute of Neurological Disorders and Stroke in 2000. He jumped head-first into neurophysiology research, and received a Ph.D. in Neuroscience from Washington University in 2006, working in the laboratory of Steven Mennerick, Ph.D. His Ph.D. research focused on the important role of the axon initial segment in generating and maintaining neuronal action potential signaling during healthy and pathophysiological states.

Dr. Meeks' long-standing interests in neuronal computation were the focus led him to pursue postdoctoral training in the laboratory of Timothy Holy, Ph.D. In his postdoctoral research, Dr. Meeks developed ex vivo procedures for studying difficult-to-access circuits in the mouse brain.  He applied these procedures to study communication between neurons in the mouse accessory olfactory system (AOS), an olfactory pathway that strongly influences mouse social and reproductive behaviors, including territorial aggression, mating, maternal behavior, and predator avoidance. In his postdoc work, Dr. Meeks developed physiological methods that allowed him to determine how neurons in the AOS extract information from the complicated blends of olfactory cues that animals encounter every day.

Dr. Meeks joined the faculty at UT Southwestern in the Department of Neuroscience in 2012.  His laboratory continues to investigate mechanisms by which the AOS influences social/reproductive behaviors. The Meeks Laboratory has several areas of interest, including identification of new kinds of pheromones (within-species chemosignals) and kairomones (across-species chemosignals). In 2016, Wayne Doyle, a graduate student in the laboratory, discovered that bile acids in animal feces are a new class of AOS ligands. Other major research interests include experience-dependent social learning, neural circuit organization, and the role of interneurons in information processing.
