Ulf Grenander (born 23 July 1923) is a statistician and a professor of applied mathematics at Brown University.

His early research was in probability theory, stochastic processes, time series analysis, and statistical theory (particularly the order-constrained estimation of cumulative distribution functions using his sieve estimator). In recent decades, Grenander contributed to computational statistics, image processing, pattern recognition, and artificial intelligence.

Honors[edit]

In 1966 Grenander was elected to the Royal Academy of Sciences of Sweden, and in 1996 to the US National Academy of Sciences. He received an honorary doctorate in 2005 from the Royal Institute of Technology of Stockholm, Sweden.[2]

Schooling[edit]

Grenander earned his undergraduate degree at Uppsala University.[3] Grenander earned his Ph.D. at Stockholm University in 1950 under the supervision of Harald Cramér.[4]

Appointments[edit]

He was active as a 1950–1951 Associate Professor at Stockholm University, 1951–1952 at University of Chicago, At 1952–1953 University of California–Berkeley, At Stockholm University 1953–1957, at Brown University 1957–1958 and 1958–1966 again at Stockholm University, where he succeeded in 1959 Harald Cramér as the Professor in actuarial science and mathematical statistics. From 1966 until his retirement, Grenander was L. Herbert Ballou University Professor at Brown University. In 1969–1974 he was also professor of Applied Mathematics at The Royal Institute of Technology.[5]
