Ilya O. Ryzhov

I am Dean's Professor of Decision Sciences in the Department of Decision, Operations, and Information Technologies at the Robert H. Smith School of Business, University of Maryland. I received my Ph.D. from Princeton University in 2011. I am a co-author (with W.B. Powell) of the book Optimal Learning, available on Amazon.

I work on decision-making under uncertainty, encompassing topics in optimization, probability, and statistics. I have a strong program of theoretical research, but have also worked on applications with the shared themes of public interest and social good, spanning problems in humanitarian logistics, medical decision-making, biomanufacturing, and fair hiring. My work has been funded by the NSF.
