Professor Rhonda Righter is a Professor and past Chair of the Department
of Industrial Engineering and Operations Research at the University of
California, Berkeley. Before coming to Berkeley she taught at the Leavey
School of Business at Santa Clara University. Her PhD is in Industrial
Engineering and Operations Research from UC Berkeley, her BS is in
applied math and business from Carnegie Mellon. Her primary research and
teaching interests are in the general area of stochastic modeling and
optimization, especially as applied to service, manufacturing,
telecommunications, and large-scale computing systems. She is an
