Sergio E. Ulloa is professor of physics in the Department of Physics and Astronomy at Ohio University. He holds a B.Sc. from UNAM in Mexico City, and a Ph.D. from SUNY at Buffalo, and held a postdoctoral position at Simon Fraser University before joining Ohio University. He is a condensed-matter theorist interested in electronic properties of nanostructures. His collaborations in the US, Germany, Argentina, and Brazil include studies of correlated systems, and his recent work focuses on the role of spin-orbit interactions in solids, especially in two-dimensional systems. He is a Fellow and Outstanding Referee of the APS and Member of the Mexican Academy of Sciences. For more information see his group’s page here.
