Tony Frederick Heinz (born 30 April 1956 in Palo Alto) is an American physicist.
Heinz studied at Stanford University, earning a bachelor's degree in 1978. He received his doctorate in 1982 at the University of California, Berkeley, in physics. From 1983 to 1995 he was at the Thomas J. Watson Research Center of IBM. He was a professor at Columbia University and is now a professor at Stanford University. He served as president of The Optical Society in 2021.
His research focuses on ultrafast laser spectroscopy (femtosecond pulses) and thus investigates dynamics at surfaces. His group investigates electronic and optical properties of a few atoms of thin two-dimensional systems (such as graphene or ultrathin crystals of transition-metal di-chalcogen compounds). His significant contributions to the condensed matter and materials physics includes discovery of room temperature excitons in 1D and 2D materials.
Heinz is one of the most cited scientists. Since 2019, the media group Clarivate counts him among the favorites for a Nobel Prize (Clarivate Citation Laureates).
