A postdoctoral position is available starting as soon as possible to characterize the spatio-temporal organization of sensori-motor cortical activity at multiple spatial scales associated with upper limb movements of behaving marmosets.  This project involves high density multi-electrode array recordings as well as calcium fluorescence imaging from motor and somatosensory cortical sites in marmosets performing natural arm and hand movements.  Facilities include a fully equipped electrophysiological laboratory with three 128-channel acquisition systems for multi-electrode recording and stimulation, calcium fluorescence imaging microscopes, and camera-based and a 3D videofluoroscopy-based motion capture systems.  Expertise in multi-site, behavioral electrophysiology and/or calcium imaging is preferred.  A strong mathematical, computational, or engineering background is also desirable.    Applicants should send a CV and names and addresses of two or three references to Dr. Nicholas Hatsopoulos, Department of Organismal Biology, University of Chicago, 1027 East 57^th Street, Chicago, IL 60637 or by e-mail to nicho@uchicago.edu.
