Ramamoorthy Ramesh (born 1960) is an American materials scientist of Indian descent who has contributed to the synthesis, assembly and understanding of complex functional oxides. In particular, he has worked on the fundamental science and technology translation of ferroelectric perovskites, manganites with colossal magnetoresistance, and multiferroic oxides with potential benefits for modern information technologies. To date, Ramesh has >675 publications with >100,000 citations, resulting in an h-index >150. He was named Citation Laureate (Thomson Reuters) for his research on multiferroics (2014).
He is currently on leave from Berkeley, serving as the Executive Vice President for Research at Rice University, where he is also a professor in the Department of Materials Science and Nanoengineering and the Department of Physics and Astronomy.
Ramamoorthy Ramesh received a B.S. in Chemistry from Madras University (1980) and a B.E. in Metallurgy from the Indian Institute of Science, Bangalore and his M.S. and Ph.D. in Materials Science and Engineering in 1985 and 1987, respectively. From 1989-1995 Ramesh was a Member of Technical Staff, Bell Communications Research (Red Bank). From 1995-1999, he became an Associate Professor in Materials Science and Engineering, University of Maryland and from 1999-2003 he was a Professor and Distinguished University Professor in Materials Science and Engineering, University of Maryland. Since 2004, he has been a Professor of Physics and Materials Science and Engineering at the University of California, Berkeley. Since his move to Berkeley, Ramesh has had a number of leadership positions including serving as the Founding Director, U.S. Department of Energy SunShot Initiative (2011-2012), the Deputy Director, Science and Technology, Oak Ridge National Laboratory (2013-2014), and the Associate Laboratory Director, Lawrence Berkeley National Laboratory (2014-2018). From 2004 onwards, he is the Purnendu Chatterjee Chair Professor in the Departments of Physics & Materials Science and Engineering at the University of California, Berkeley.
