Research Interests

Dr. Crowder’s research focuses on how biological visual systems see form and motion. 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 , neuroinformatics, psychophysics, and computer modeling.
