Dr. David Whitney joined MPFI as a post-doc in the Fitzpatrick lab in September 2013. Using cutting-edge optical methods to interrogate neural activity, his research focuses on understanding how neural response properties, such as orientation-selectivity, emerge in the visual cortex during development.
Prior to joining the Fitzpatrick lab, Dr. Whitney earned his Ph.D. in Biological Sciences at Carnegie Mellon University with Dr. Justin Crowley and Dr. Seong-gi Kim. His dissertation work used longitudinal optical imaging of intrinsic signal to demonstrate that cortical feature maps in ferret visual cortex remain largely stable throughout the developmental critical period, and are robust to perturbation.
