SUMMARY OF RESEARCH INTERESTS:

    My research combines psychophysical experiments with computational modeling to examine mechanisms underlying visual processing, with an eye for building models that are consistent with results in the electrophysiological literature. At present I am primarily studying human motion perception with respect to the ability to judge heading and 3D object motion.
