My general interest is in computational models of early visual
processing. Within this context I work on models which represent human
performance in basic perceptual tasks. A version of my vita is on-line. For a brief statement of my research interests click here
I received my Ph.D at the
University
of Texas at Austin in Psychology under the mentorship of Wilson S. Geisler,
III. While at the Center for Vision and Image Sciences in Austin, I used psychophysical tasks to test hypotheses concerning spatial
vision, light adaptation and contrast adaptation. (For an abstract of a talk
I gave at the 1994 Annual Optical Society of America convention click here. To view a draft of the dense 12 minute talk click here.)
At The University of Pennsylvania (map), I have continued to make psychophysical measurements, but I am
also learning the retinal anatomy which underlies the measured behavior. As
a result, I am attempting to integrate functional aspects of the visual
system which have been measured psychophysically with structural aspects of
the visual system which have been measured anatomically. The psychophysical
measurements are made in Jacob Nachmias' lab (Psychology) and the anatomical measurements
are made in Peter Sterling's lab (Neuroscience).
I am about to begin the second phase of my stay at Penn, by devoting my time completely to learning about and modeling retinal processes in the Neuroscience department.
Because my memory leaves something to be desired, I have been creating a set of hypertext documents which describe retinal anatomy, various formulas which are vision-oriented and other relevant neuroscience information.
