Biography: 

Bella Bose received the B.E. degree in electrical engineering from Madras University, Madras, India in 1973, the M.E. degree in electrical engineering from Indian Institute of Science, Bangalore, in 1975, and the M.S. and Ph.D. degrees in computer science and engineering from Southern Methodist University, Dallas, TX, in 1979 and 1980, respectively.

Since 1980, he has been with the Department of Computer Science, Oregon State University, Corvallis, Oregon, where he is a Professor. In 1996 he was awarded the College of Engineering Research Award for Outstanding and Sustained Research Leadership. His current research interests include error control codes, fault-tolerant computing, parallel processing, and computer networks.

Bose is a Fellow of both ACM and IEEE.

Research Description
My current research interests are in error control codes, VLSI testing, parallel processing, and fault tolerant computing.

We are developing efficient codes for unidirectional/asymmetric errors in the area of error control coding. Simple and efficient design of encoder/decoder algorithms are also being studied. Further, we have been developing efficient design methods for balanced codes, where each codeword contains equal number of 1's and 0's.

In the area of VLSI testing, we are investigating new and efficient methods for compression testing. Our research also involves the application of these schemes for built-in-self-testing in VLSI systems. Efficient design of communications algorithms, mapping algorithms, etc., with or without some faulty nodes in different networks are some of the parallel processing research problems that we are currently investigating. Furthermore, using coding theory, some topological properties of different networks are being developed.
