Jim Gates


Jim Gates, Distinguished University and Regents Professor

Sylvester James (Jim) Gates, Jr., is a member of the National Academy of Sciences, recipient of the National Medal of Science, and has had a very long and successful career as a theoretical physicist and an educator. He is well known for his work on supersymmetry, supergravity, and superstring theory. From 1985 - 2016 he was a faculty member at University of Maryland, College Park as a University System Regents Professor, the John S. Toll Professor of Physics, the Director of the String and Particle Theory Center, and Affiliate Professor of Mathematics. He also served on the U.S. President’s Council of Advisors on Science and Technology (PCAST) under President Barack Obama. He served on the Maryland State Board of Education from 2009-2016, and the National Commission on Forensic Science from 2013-2016. Sensitive to diversity issues over the duration of his career, in 1995 he authored an essay entitled "Equity versus Excellence: A False Dichotomy in Science and Society." This avenue of his writings eventually led to a work "Thoughts On Creativity, Diversity and Innovation in Science and Education" that was cited by the U.S. Supreme Court of the United States in its 2016 decision in the case  'Abigail N. Fisher v. University of Texas at Austin, et. al.'  Gates has engaged efforts to look at social justice themes within physics, physics education and policy.
