Biography
editGeman was born and raised in Chicago. He was educated at the University of Michigan (B.S., Physics, 1971), Dartmouth Medical College (MS, Neurophysiology, 1973), and the Massachusetts Institute of Technology (Ph.D, Applied Mathematics, 1977).
Since 1977, he has been a member of the faculty at Brown University, where he has worked in the Pattern Theory group, and is currently the James Manning Professor of Applied Mathematics. He has received many honors and awards, including selection as a Presidential Young Investigator and as an ISI Highly Cited researcher. He is an elected member of the International Statistical Institute, and a fellow of the Institute of Mathematical Statistics and of the American Mathematical Society.[7] He was elected to the US National Academy of Sciences in 2011.
Work
editGeman's scientific contributions span work in probabilistic and statistical approaches to artificial intelligence, Markov random fields, Markov chain Monte Carlo (MCMC) methods, nonparametric inference, random matrices, random dynamical systems, neural networks, neurophysiology, financial markets, and natural image statistics. Particularly notable works include: the development of the Gibbs sampler, proof of convergence of simulated annealing,[8][9] foundational contributions to the Markov random field ("graphical model") approach to inference in vision and machine learning,[3][10] and work on the compositional foundations of vision and cognition.[11][12]
