I  investigate the motion system as a model to study the link between sensation, perception, and decision making. To this end I use a combination of psychophysical tasks (humans and monkeys) as well as single and multi-electrode recording techniques in awake behaving monkeys. Some of the main research topics are:
The relation between single unit firing rate and behavioral choice  on a trial by trial basis.

The neural basis of chromatic motion processing has been (and still is) a matter of debate for almost thirty years. We investigated whether chromatic motion sensitivity of neurons in macaque area MT match monkey psychophysical sensitivity using the opposed motion stimulus (Cavanagh P, Anstis S, 1991, Vis. Res., 31: 2109-2148). Our findings testify that area MT is indeed a principal component of the neuronal substrate for color-based motion processing.

However, we also found a yet unreported difference between human and monkey psychophyisical chromatic motion sensitivity.
