The overall goal of my research is to understand where and how the retina processes the visual signal. Traditionally, scientists assumed each neuron integrated signals from upstream neurons and then relayed that signal to downstream neurons as a single “channel” of information. However, we show that the signal can diverge due to computations that occur in different compartments of the same cell. This allows a single neuron to output two different signals onto two different downstream cells, allowing for greater processing of the visual signal with a fewer number of cells.

I am interested in how intrinsic properties of neurons contribute to specific neuronal computations. In particular, I am studying how active conductances and the excitability of a neuron contribute to the Suppressed-by-Contrast feature selectivity of a novel retinal ganglion cell.

Direct retinal projections to the brain innervate an extensive number of brain areas. Identifying the functional selectivity RGCs projecting to hypothalamus would provide crucial insights into the role of visual input into related behaviors. Thus I am exploring the RGC subtypes and visual cues that may drive innate hypothalamic behavior.

I am interested in describing neural computations in the retina as they relate to health and disease. My main focus is on using calcium imaging and biophysical models to understand retinal neurovascular coupling and how it may be perturbed in diabetic retinopathy. Other projects with which I am or have been involved include modeling the circuit dynamics of the nNOS-2 amacrine cell, modeling the statistical properties of bipolar cell-to-RGC neurotransmission, and using our knowledge of RGC typology to improve retinal prostheses.
