MIT ChemE welcomes new assistant professor William A. Tisdale

William A. TisdaleOn January 1, 2012, MIT Chemical Engineering will welcome its latest faculty member: Assistant Professor William A. Tisdale. Tisdale received his bachelor’s degree in Chemical Engineering (magna cum laude) from the University of Delaware in 2005. In July 2010, he completed his Ph.D. in chemical engineering at the University of Minnesota under the joint direction of Professors Eray Aydil, David Norris, and Xiaoyang Zhu (Department of Chemistry). Most recently, Tisdale was a postdoctoral associate with Professor Vladimir Bulović in the Research Laboratory of Electronics at MIT, where he studied exciton diffusion and energy transfer in nanostructured thin films.

Tisdale is the recipient of an NSF IGERT Fellowship and a University of Minnesota Doctoral Dissertation Fellowship. His research interests surround excited state dynamics near surfaces and interfaces and the application of this understanding toward development of novel photovoltaic and optoelectronic technologies.

Professor Tisdale’s research program’s theme is the understanding and controlling of the flow of energy in nanostructured materials. His laboratory will investigate excitonic energy transfer, charge and heat transport, and charge separation at interfaces between organic and inorganic nanostructured materials that are promising components of next-generation solar cells, high efficiency lighting, and flexible electronics. A central aim of his research is to correlate morphology and disorder with dynamics and electrical and optical properties on a local scale. He uses a variety of tools to address these challenges, with particular emphasis on ultrafast spectroscopy and nonlinear optical imaging in both the near and far field.
