Harry Atwater is the Howard Hughes Professor of Applied Physics and Materials Science at the California Institute of Technology and serves as Director of the DOE Joint Center for Artificial Photosynthesis. His scientific interests have two themes: photovoltaics and solar energy as well as plasmonics and optical metamaterials. His group has created new high efficiency solar cell designs and have developed principles for light management in solar cells. Prof. Atwater is an early pioneer in nanophotonics and plasmonics; he gave the name to the field of plasmonics in 2001. He has authored or co- authored more than 400 publications cited in aggregate > 33,000 times and his group’s advances in the solar energy and plasmonics field have been reported in Scientific American, Science, Nature Materials, Nature Photonics, and Advanced Materials. He is co-founder and chief technical advisor for Alta Devices, a venture-backed company in Santa Clara, CA, that holds the current world record for 1 Sun single junction solar cell efficiency and that is currently transitioning high efficiency/low cost GaAs photovoltaics technology to manufacturing and large-scale production. He serves as Editor in Chief for the journal ACS Photonics, and is Associate Editor for the IEEE Journal of Photovoltaics, and in 2006 he founded the Gordon Research Conference on Plasmonics, which he served as chair in 2008. Harry Atwater is a Fellow of the Materials Research Society, and Member of US National Academy of Engineering and National Academy of Inventors. He has been honored by awards, including (2016) APS David Adler Lectureship for Advances in Materials Physics, (2014) Julius Springer Prize in Applied Physics, (2014) ISI Highly Cited Researcher, (2013) Fellowship from the Royal Netherlands Academy of Arts and Sciences, (2012) ENI Prize for Renewable and Non- conventional Energy, SPIE Green Photonics Award (2012), among others. Prof. Atwater has worked extensively as a consultant for industry and government and has actively served the materials community, including Material Research Society Meeting Chair in 1997, AVS Electronic Materials and Processing Division Chair in 1999, Materials Research Society President in 2000, and Board of Trustees of the Gordon Research Conferences. Prof. Atwater received his B. S., M. S. and Ph.D. degrees from the Massachusetts Institute of Technology. He held the IBM Postdoctoral Fellowship at Harvard University from 1987-88, and has been a member of the Caltech faculty since 1988.
