vision postdoc position at Columbia

[Ning Qian]

         Postdoctoral Position in Visual Psychophysics
             Center for Neurobiology and Behavior 
                     Columbia University
                         New York, NY

A postdoctoral fellowship position in Visual Psychophysics is
available immediately in my lab at Columbia University.  The
individual will participate in psychophysics projects that investigate
the mechanisms of motion detection, stereoscopic depth perception and
motion-stereo integration.  There will be close interactions between
these projects and the related computational modeling projects in the
same lab.  The details of our research interests and publications can
be found at the web site listed below.  The funding for the position
is available for two years with the possibility of renewal.
Applicants should have a strong background in visual psychophysics and
should be able to write programs (or adapt our current psychophysics
software package) for generating visual stimuli.  Please send a CV,
representative publications and two letters of recommendations to:
