Erik Brunvand Associate Professor www.cs.utah.edu/~elb elb@cs.utah.edu

Erik Brunvand received a B.S. in Computer Science and a B.S. in Mathematics at the University of Utah in 1982, his M.S. in Computer Science at the University of Utah in 1984, and his Ph.D. in Computer Science at Carnegie Mellon University in 1991. Professor Brunvand joined the Department of Computer Science in 1990. He has interests in computer architecture and VLSI systems in general, and self-timed and asynchronous systems in particular. One aspect of his research involves compiling concurrent communicating programs into asynchronous VLSI circuits. The current system allows programs written in a subset of occam, a concurrent messagepassing programming language based on CSP, to be automatically compiled into a set of self-timed circuit modules suitable for manufacture as an integrated circuit. His most recent research project is involved with designing custom hardware to accelerate ray tracing graphics. The end goal of this research is to develop technology to enable commodity ray tracing-based graphics chips that can replace or augment today’s GPUs and enable higher quality and more realistic graphics capabilities for future computers.
