Douglas was born in
Baton Rouge, Louisiana, the son of Nancy and
Ronald G. Douglas, a
mathematician specializing in
operator algebras. He received his
bachelor's degree in physics from
Harvard University. He then went to
Caltech and received a
PhD in physics in 1988 under
John Schwarz, one of the developers and leading researchers in
superstring theory. After completing his PhD, Douglas was a postdoc at the
University of Chicago for one year, then moved to
Rutgers University in 1989 with
Dan Friedan and
Steve Shenker to help start the New High Energy Theory Center (NHETC). He was promoted to assistant professor in 1990 but spent his first year visiting the
École Normale Supérieure and the
MIT Artificial Intelligence Laboratory. He became an associate professor at Rutgers in 1995, and left for a year in 1997–1998 to take up a permanent position at the
Institut des Hautes Études Scientifiques. He then returned to Rutgers and in 2000 became the director of the NHETC. In 2008, Douglas moved from Rutgers to become the first permanent member of the
Simons Center for Geometry and Physics, a research center at
Stony Brook University. In 2012, Douglas left Stony Brook University to work for
Renaissance Technologies, the famous quantitative hedge fund. He returned to academia in 2020 and is presently a long-term visitor at the Center of Mathematical Sciences and Applications at
Harvard University, doing research on machine learning and its applications in scientific research. Douglas is best known for the development of
matrix models (the first nonperturbative formulations of string theory), for his work on
Dirichlet branes and on
noncommutative geometry in string theory, and for the development of the statistical approach to string phenomenology. He was on the team (led by
Gerald J. Sussman) that built the
Digital Orrery, a special-purpose computer for computations in
celestial mechanics, and maintains an active interest in
computer science. He is also very active in organizing schools and workshops, for example at
Les Houches, Cargese, and the KITP Santa Barbara. Douglas received the 2000
Sackler Prize in theoretical physics and has been a Gordon Moore Visiting Scholar at Caltech and a
Clay Mathematics Institute Mathematical Emissary. In 2012 he became a fellow of the
American Mathematical Society. He has a long association with the
Institut des Hautes Études Scientifiques, as a Louis Michel Visiting Professor from 2000 to 2008, and as chairman and President of the Friends of IHES from 2013 to 2021. Douglas is married and has two children. His wife, Nina Ilieva Douglas, is an artist. Her sculpture of
Alexander Grothendieck is on permanent display at the IHES. ==References==
