Gilliard, Jr, Robert J. - Massachusetts Institute of Technology

个人简介

Dr. Robert J. Gilliard, Jr. is the Novartis Professor of Chemistry at the Associate Rank in the Department of Chemistry at Massachusetts Institute of Technology (MIT). Before moving to MIT, he served on the faculty at the University of Virginia. He obtained his bachelor’s degree from Clemson University and doctorate from the University of Georgia. He was a UNCF-Merck Postdoctoral Fellow and a Ford Foundation Postdoctoral Fellow where he completed joint postdoctoral studies at both the Swiss Federal Institute of Technology (ETH Zürich) and Case Western Reserve University. Professor Gilliard is the recipient of the American Chemical Society Harry Gray Award “for his outstanding achievements in the development of creative synthetic strategies for low-oxidation-state main-group inorganic materials with unusual bonding and photophysical properties.” He won the Organometallics Distinguished Author Award, which recognizes authors of exceptional articles that emphasize the importance of organometallic chemistry and have made a profound impact on the field. Professor Gilliard received the honor “in recognition of dynamic and ground-breaking research in main-group chemistry, in particular on novel complexes and electronic structures of magnesium and beryllium.” In the past, he has also been named to various lists of notable scientists by media such as Chemical and Engineering News and Forbes Magazine. Professor Gilliard has authored 60 publications and patents applications. He has been an invited speaker at over 80 colleges/universities and scientific conferences in the United States and abroad. He is member of the editorial advisory board at leading international journals, including Inorganic Chemistry, Chemical Communications, Chem Catalysis, ChemistryEurope, and Angewandte Chemie. Professor Gilliard consults on matters related chemical processes, science policy, educational policy, faculty and student mentoring, and diversity, equity, and inclusion.

研究领域

Professor Gilliard specializes in the chemical synthesis of new molecules that impact the development of new catalysts and reagents, including the discovery of unknown transformations of environmentally-relevant small-molecules [e.g., carbon dioxide (CO2), carbon monoxide (CO), and dihydrogen (H2)]. In addition, he investigates the design, characterization, and reactivity of boron-based luminescent and redox-active heterocycles for use in optoelectronic applications (e.g., stimuli-responsive materials, thermochromic materials, chemical sensors).
