My research in the CAD area includes physical layout, timing verification, and delay fault test for high-speed circuits. My research in high-speed networking includes heterogeneous high-performance computing over high-speed networks, PC and workstation clustering, broadband connections to homes and desktops, and all optical networks. My research in multimedia applications includes video transmission over ATM networks, video-on-demand servers, distance learning using multimedia technologies, and mass storage systems for both video-on-demand and Internet Web servers.

For the next few years, I will focus my research on run-time optimization dynamic compilation/optimization techniques. Run-time optimization systems use run-time feedback information, via various profiling techniques, to identify hot code fragments and performance bottlenecks. Once the important code fragments are identified, the system modifies the binary on-the-fly to tune the program for its current usage and for the current processor it runs on. Run-time optimization systems are very useful for migrating applications to new architectures or new micro-architectures.

My main research research effort is on the design of future generations of high-performance computer systems, which include both microprocessors and multiprocessors. I am interested in issues related to their machine architectures, machine organizations, and compilation techniques. I am also interested in improving the performance of Internet applications, especially the performance of large Java applications.

My main research interests broadly lie in the area of computer networks and real-time, distributed, multimedia systems. One challenging and critical research problem in this area is how to provide Quality-of-Service (QoS) guarantees to support real-time multimedia applications in the emerging high speed, integrated services packet networks. My research has focused primarily on issues related to this central theme and addresses them from both the standpoint of network systems and of application or end-host systems.
