Dr. Carter recently accepted a joint appointment as a professor in the Computer Science and Engineering Department of the University of California at San Diego and a Senior Fellow at the San Diego Supercomputing Center. Prior to that, he had worked at IBM's Watson Research Center for almost 20 years, taking sabbatical leaves to UC Berkeley, Penn State University, the University of Colorado. His research interests are remarkably similar to Dr. Alpern's, and they are frequent collaborators.
