Areas of research include biophysical mechanisms underlying information processing; experimental and modeling studies of the visual system; the circuitry, computational function, and modeling of the olfactory cortex; the theory of collective circuits for biological and machine computations; experimental studies of the circuitry and control of insect locomotor function; the relation between problem complexity communication, and computation in parallel machines; modeling and representation of physical objects for the general analysis of images; and the use of optical devices in parallel computational hardware.
