Stanley Osher (born April 24, 1942) is an American mathematician, known for his many contributions in shock capturing, level-set methods, and PDE-based methods in computer vision and image processing. Osher is a professor at the University of California, Los Angeles (UCLA), Director of Special Projects in the Institute for Pure and Applied Mathematics (IPAM) and member of the California NanoSystems Institute (CNSI) at UCLA.

Education and career

Osher received a bachelor's degree from Brooklyn College in 1962. He continued his studies at New York University, where he received a master's degree in 1964{{cite web|url=https://www.math.ucla.edu/~sjo/oshercv.doc|title=Curriculum vitae|access-date=2025-04-24}} and completed his Ph.D. in 1966.{{mathgenealogy|11645}}

After two years working at the Brookhaven National Laboratories, he joined the University of California, Berkeley as an assistant professor of mathematics in 1968. He moved to Stony Brook University as an associate professor in 1970, and there was promoted to full professor in 1975. He moved again to the University of California, Los Angeles Department of Mathematics in 1977.

He co-founded a spinoff company, Cognitech, in 1988, and remained affiliated with Cognitech until 1995.
