   My research interest is in the area of <a href=http://www.cs.wisc.edu/~zhichen/lang.html> programming languages</a> and performance issues in parallel and distributed systems.   Recently, I have been studying techniques to detect and eliminate performance bottlenecks in Distributed Shared-Memory Systems. I have combined the  <a href="http://www.cs.wisc.edu/~paradyn/"> Paradyn Performance Tool</a> with Blizzard of the <a href="http://www.cs.wisc.edu/~wwt/"> Wisconsin Wind Tunnel</a> on both the Thinking Machine CM-5 and the Cluster of Workstations (COW).  <p>
