Ward Whitt

from Wikipedia, the free encyclopedia

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

Education and career

Whitt grew up in Bozeman ( Montana ) and studied at Dartmouth College with a bachelor's degree in 1964 and at Cornell University , where he received his doctorate in operations research with Donald Iglehart in 1969 (weak convergence theorems for queues in heavy traffic). In 1968/68 he was at Stanford University (Visiting Assistant Professor) and from 1969 to 1977 at Yale University , from 1973 as Associate Professor. From 1977 to 2002 he was at Bell Laboratoriesand their successors. First he was in the Operations Research department in Holmdel, where he worked on the development of the Queuing Network Analyzer (QNA), then in the math research center in Murray Hill and from 1996 at the ATT Labs in Florham Park. Since 2002 he has been a professor at Columbia University (Faculty of Industrial Engineering and Operations Research).

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

Prizes and awards

Whitt is also a member of the National Academy of Engineering and an INFORMS Fellow and ATT Fellow.
