I have been a professor in the Department of Computer Science at the University of Illinois since 1987, as an assistant, associate, full, adjunct, and now research professor. Before that, I worked for Bell Labs. My research interests lie in data management and security; more specifically, I am interested in trust management and scientific data management. I served as SIGMOD vice chair from 2001-5, and as an editor for ACM Transactions on Database Systems from 1994-2004. I have also served as an editor for IEEE Transactions on Knowledge and Data Engineering, and am currently on the editorial board of ACM Transactions on the Web.I received a Presidential Young Investigator Award from the National Science Foundation in 1989 and Xerox Awards for Faculty Research in 1990 and 1997. I received my PhD in Computer Science from Stanford University in 1987.
