I came to MIT as a postdoctoral fellow on a NIH Fogarty Fellowship in 1994.At present I am a research scientist at the Picower Institute of Learning and Memory at MIT and hold joint appointments as an Instructor in Radiology, Harvard Medical School and Assistant Neuroscientist at the Martinos Center for Biomedical Imaging, Massachusetts General Hospital, Charlestown, MA. The focus of my research is cortical plasticity and dynamics of interaction between top-down (or internal states) with bottom up (or external) inputs that guide behavior. I am also interested in understanding the influence of past experience on short term learning in cortical networks. I use diverse approaches to investigate these issues that include high resolution fMRI, optical imaging and multi-electrode electrophysiology.I have published extensively in leading journals including Science, Nature and Neuron and serve as an ad-hoc reviewer for numerous journals.
