Presenter: Professor William A. Tisdale, Chemical Engineering, Massachusetts Institute of Technology
Hybrid organic-inorganic semiconductor nanomaterials – including colloidal quantum dots (QDs), 2D halide perovskites, and metal organochalcogenides – are excitonic materials with applications ranging from solar cells to light-emitting devices to quantum computing and quantum cryptography. In these emerging materials, the combination of quantum and dielectric confinement, strong exciton-phonon coupling, and dimensionality reduction offer unprecedented opportunities for controlling light- matter-charge interactions through chemistry. In this talk, I will describe recent work from my lab on the synthesis and photophysics of hybrid semiconductor nanomaterials and our evolving understanding of how structure and chemical functionalization influence excited state dynamics.

Dr. Will Tisdale is the Warren K. Lewis Professor of Chemical Engineering at MIT, where he has been teaching and leading a research team since 2012. His research program is focused on the discovery of hybrid organic-inorganic nanomaterials capable of transporting energy in new ways, and on the use and development of ultrafast laser spectroscopy methods and advanced optical microscopy techniques for probing dynamics at the nanoscale. Will’s contributions to research have been recognized by the Presidential Early Career Award for Scientists and Engineers (PECASE), an Alfred P. Sloan Fellowship, the Camille Dreyfus Teacher-Scholar Award, the DOE Early Career Award, the NSF CAREER Award, and the AIChE NSEF Young Investigator Award. For his dedication to undergraduate teaching Will received MIT’s highest honor, the MacVicar Fellowship, as well as the student-selected Baker Award and the School of Engineering’s Amare Bose Award.
