Erin L. Barnhart

Erin L. Barnhart serves as an Assistant Professor of Biological Sciences at Columbia University. Her office is located at 731 Mudd, Mail Code: 2401, United States, and she maintains the Barnhart Lab which focuses on bridging the gap between systems neuroscience and cell biology.

Dr. Barnhart's research centers on understanding how diverse neuronal processing properties emerge from dynamic molecular interactions in vivo. Her work specifically examines how organelles—particularly mitochondria and the endoplasmic reticulum—respond to physiological neuronal activity and subsequently tune neuronal computations. She employs sophisticated imaging and genetic techniques to simultaneously measure and manipulate neuronal activity and subcellular elements within well-defined Drosophila motion vision circuits.

The Barnhart Lab explores uncharted territory in neuroscience, linking molecular and cellular dynamics to large-scale neural circuit function in vivo. Her research program represents a unique integration of cell biology and neuroscience approaches to understand the fundamental mechanisms of neuronal function.
