Donald F. Towsley

Distinguished University Professor
(413) 545-0207


Networks, performance analysis.


Professor Towsley's research spans a wide range of activities from stochastic analyses of queueing models of computer and telecommunications to the design and conduct of measurement studies. He has performed some of the pioneering work on the exact and approximate analyses of parallel/distributed applications and architectures. More recently, he pioneered the area of network tomography and the use of fluid models for large networks. He has published extensively, with over 150 articles in leading journals.


PhD Comptuer Science, University of Texas (1975), BA Physics, University of Texas (1971).  Professor Towsley first joined the faculty at the University of Massachuseets in  the Department of Electrical and Computer Engineering  in 1976 and moved to the College of Information and Computer Sciences in 1986. He was named University Distinguished Professor of Computer Science in 1998.  Professsor Towsley  was a Visiting Scientist at the IBM T.J. Watson Research Center, (1982-83, 2003), INRIA and AT&T Labs - Research (1996-97), and Cambridge Microsoft Research Lab (2004); a Visiting Professor at the Laboratoire MASI, Paris, (1989-90).
