About Us
Physiology and Neurobiology is a multidisciplinary research department at the University of Connecticut. Our mission is to promote research and education that is innovative, collaborative, and centered on cutting-edge science. The department promotes this goal by bringing together researchers and educators focused on the molecular, cellular, and circuit-based mechanisms that underlie diverse functions orchestrated by the brain and body. By integrating work across the spectrum of Physiology and Neurobiology, we aim to advance our understanding of brain-body functions and interactions under normal conditions and disease.
Molecular & Cellular Physiology
This research focuses on the basic cellular mechanisms (e.g., intracellular signaling, gene regulation, protein interactions) that underlie neural circuit and synaptic functions, heterogeneity within classical cell types, ion channel physiology, cardio-respiratory physiology, sensory receptor signaling, reproduction, and endocrinology. Scientific questions of interest are interrogated using several model systems in combination with diverse technical approaches.
