Ronitt Rubinfeld is a professor of electrical engineering and computer science at the Massachusetts Institute of Technology and a member of MIT’s Computer Science and Artificial Intelligence Laboratory. Her research focus is the theory of computation, and much of her current work involves randomized and sublinear time algorithms. A graduate of the University of Michigan, she earned a Ph.D. in computer science in 1990 at the University of California at Berkeley under the supervision of Manuel Blum. She held a postdoctoral research fellowship at Princeton University, followed by a year as a visiting research scholar at Hebrew University in Jerusalem. Dr. Rubinfeld joined the Cornell University computer science faculty as an assistant professor in 1992 and was promoted to associate professor six years later. She held visiting appointments at MIT and at the IBM Almaden Research Laboratory in San Jose, California, while at Cornell, and in 1999, she accepted a position as a senior research scientist at the NEC Research Laboratories in Princeton. She became a fellow at the Radcliffe Institute for Advanced Study in early 2004 and was named to her MIT professorship later that year. Dr. Rubinfeld has been the recipient of an Office of Naval Research Young Investigator Award, a Cornell Association for Computer Science Undergraduate Faculty of the Year Award as well as a Cornell College of Teaching Engineering Award, a National Science Foundation Career Award, and an Alfred P. Sloan Research Fellowship. A member of the editorial boards of the Theory of Computing Systems Journal, Information and Computation, and Algorithmica, she was guest co-editor of the Journal of Computer Systems Sciences special issue on the 1996 Symposium on the Theory of Computing. She has published more than twenty-five papers in scientific journals.
