Dr. Schiff has a long history of leading complex research projects that bring together academics, industry scientists and other partners to discover solutions to society’s energy-related problems. He has been a professor of physics at ϲ since 1981, leading interdisciplinary research groups and collaborating with laboratories from other universities and private organizations throughout the world. He has been a principal investigator for externally funded research projects from government agencies (Department of Energy, National Science Foundation and the Empire State Development Corp.) and corporations (United Solar Ovonic LLC, Boeing Inc., First Solar Inc., and SRC Inc.).

During his time at ϲ, he has spent half-year sabbaticals at Xerox Palo Alto Research Center and at Innovalight, Inc., a startup company. From 2014-1017, he served concurrently as a program director at ARPA-E, an agency of the Department of Energy. There he initiated the SHIELD research program of a dozen research projects for development of inexpensive efficiency retrofits for legacy single pane windows. He also supervised a portfolio of additional projects on solar energy conversion and other energy technologies.

Schiff’s own research accomplishments include development of low-mobility solar cell device physics for thin film solar cells such as perovskites, amorphous silicon, and cadmium telluride. His fundamental physics contributions include work on electronic transport and defects in semiconductors as well as on plasmonics. He is co-author of more than 100 refereed research publications with more than 4,000 citations and he is co-inventor on three U.S. patents. He is a Fellow of the American Physical Society.
