Biography: 

Ben Lee received the B.E. degree in Electrical Engineering from the State University of New York (SUNY) at Stony Brook, New York, in 1984 and the Ph.D. degree in Computer Engineering from The Pennsylvania State University, University Park, in 1991. He is currently a professor of Electrical and Computer Engineering at Oregon State University.

In 2000, he was a visiting faculty at Information and Communications University (ICU) in Taejon, Korea. Lee received the Loyd Carter Award for outstanding and inspirational teaching from the OSU College of Engineering in 1994. He is currently on the program committee for 2003 International Conference on Parallel Distributed Computing and 2004 Pacific Rim International Symposium on Dependable Computing. His research interests include wireless computing, computer architecture, parallel and distributed systems. His current interests are delivering multimedia steams in wireless campus networks using Cellular IP, designing high-speed network interfaces, and dynamic multithreaded architectures.

Research Interests: 

Research Areas
Computer architecture, parallel processing, dataflow architectures, processor allocation in multiprocessor systems, multithreaded systems, and network multimedia systems

Research Description
My research areas encompass computer architecture, high-speed communication, and micro-mobility protocols. In computer architecture, we are researching on dynamic multithreading that allows multiple threads to be generated on the fly and execute them on a superscalar processor with support for checking dependencies among threads. For high-speed communication, there has been much research effort toward low-latency communication protocols and network interfaces. Since communication protocols closely interact with the kernel, device driver, and network interface, these interactions must be properly captured to evaluate the protocols and to improve on them. My research focuses on the design of high-speed communication systems using complete system simulation to capture and analyze all aspects of communication performance. In particular, we are looking at ways to make network interfaces less peripheral to improve the performance. For micro-mobility protocols, handoff delay is one of the most critical issues. In particular, we are interested in how these handoff delays affect the delivery of multimedia steams in wireless campus networks. We are currently looking at ways to minimize handoff delays by dynamically adjusting when and how handoffs should occur.

Applications of Research
Solving these issues are critical to making processors run faster, communication systems to speedup delivery of data, and viewing of high quality multimedia data on portable devices.
