Thesis Advisor: Timothy Ebner, M.D., Ph.D.
The goal of my thesis research is to further the understanding of cerebellar physiology. Specifically, my work focuses on investigating the way in which information is spatially represented and integrated into the cerebellar circuitry. In pursuit of this goal, I employ techniques including autofluorescence and calcium dye optical imaging as well as electrophysiology and optogenetics, all of which are performed in vivo.
