Research Interests

Aging, Electrophysiology (ERGs & VEPs), Color Vision, Psychophysics

Human electrophysiology serves to better understand the visual system and helps diagnose many pathological conditions. It has applications in clinical objective measurements of visual function as well as in correlating psychophysical studies with physiology. Color vision serves to decode the spectral information, carried in every natural scene, and plays a fundamental role in everyday life as many of our experiences and actions rely on it. The main goal of my research is to fully understand the visual mechanisms and offer better prognostics for today’s aging population, using psychophysics and human electrophysiology.
