I conduct basic research, using eye tracking and computer-based tasks, to investigate visual function and motion perception resulting from normal and abnormal development of the human visual system.
All visual input must be processed by the retinas before transmission to the visual cortex of the brain. However, eye movements are constantly directing the retinas to different objects in the environment. Yet, despite this incessant motion of the retinae, the environment is usually perceived as stationary.
A number of neuro-ophthamic conditions can produce continuous, pathological oscillations of the eyes (a sign called nystagmus) that may or may not result in an illusory motion of the environment (a symptom called oscillopsia).
The objective of my current research is to relate eye movements to measures of visual function and motion perception, in those with and without nystagmus, in an effort to better understand the perception of stationarity, oscillopsia and the consequences of inappropriate motion of the eyes
