Dr. David S. L. Wei
Professor Wei received his Ph.D. in computer science from the University of Pennsylvania, in 1991.
Dr. Wei
is a senior member of the IEEE, the Computer Society, and the
Communications Society.
Professor Wei has been working in the field of computer science for
more than 25 years. Currently, his
research mainly focuses on parallel, distributed, mobile and
power-aware computing, and
quantum computing and communications.
- Mobile and Power Aware Computing
- Quantum Computing and Communications
- Optical Networking
- Parallel and Distributed Processing
I have worked on some fundamental problems in the areas of parallel and
distributed processing, mobile computing, and optical networking.
My contributions have
helped advance the frontier of knowledge in those areas.
In particular, I have worked in the
areas of routing and sorting, parallel parsing, task scheduling,
distributed systems, mobile computing , and WDM.
The fusion of computer and communications
is redefining the way we do computing. Though there has been significant
progress in interconnection mechanism and data transmission technology,
new styles of software design, including algorithms, operating systems,
compilers, have lagged behind. To make networked computing
effective, efficient, and easily programmable,
my current research also focuses on developing efficient algorithms,
system software and tools.
