Research Interests

Dr. Crowder’s research focuses on how the brain processes visual information, and how animals use this information to make perceptual decisions. This work includes the characterization of normal visual function as well as visual deficits that result from abnormal vision during development. Techniques used in the laboratory include electrophysiology, optogenetics, behavioral tasks in transgenic mice, psychophysics, and computer modeling.
