Ward Whitt

Ward Whitt ( born January 29, 1942 in Buffalo ( New York)) is an American mathematician.

Whitt grew up in Bozeman (Montana) and studied at Dartmouth College with a bachelor 's degree in 1964 and from Cornell University, where he received his doctorate in 1969 in Operations Research at Donald Iglehart ( Weak convergence theorems for queues in heavy traffic ). 1968/68 he was at Stanford University ( Visiting Assistant Professor ) and from 1969 to 1977 at Yale University, from 1973 as Associate Professor. 1977 to 2002 he was at Bell Laboratories and its successor. At first he was in the Department of Operations Research in Holmdel, where he worked on the development of the Queueing Network Analyzer ( QNA ), then in mathematical research center in Murray Hill and from 1996 to the ATT Labs in Florham Park. Since 2002 he is a professor at Columbia University (Faculty of Industrial Engineering and Operations Research ).

It deals with queuing theory, stochastic processes and stochastic analysis of telecommunication systems.

In 2001 he received the John von Neumann Theory Prize and the 2003 Frederick W. Lanchester Prize -. He is a member of the National Academy of Engineering. He is a Fellow of INFORMS and ATT Fellow.
