General Information
I am an Associate Professor of Computer Science at the University of Utah, and a faculty member of the SCI Institute.
Upon arriving at Utah in October 2003, I started the Visualization and Geometric Computing (VGC) group that at any given time includes a number of post-doc, graduate, and undergraduate students. We often also have both short and long-term visitors in our lab.
I received a B.S. in mathematics from the Federal University of Ceara (Brazil), M.S. and Ph.D. degrees in Computer Science from the State University of New York at Stony Brook. Right after graduation I was a post-doc in the applied mathematics & statistics department at Stony Brook.
I spent several years in industry before becoming a full-time faculty member. During this time, I had the opportunity to be officially or un-officially associated with the following institutions: IBM, AT&T, Sandia, LLNL, Stony Brook, OGI, and Princeton.
