Josh Chover died on October 11, 2020. He received the PhD from the University of Michigan in 1952. After three years at Bell Labs and one year at the Institute for Advanced Study in Princeton, he joined our faculty in 1956. He was Chair of the Department fom 1977-79. Josh started our probability group by hiring Peter Ney.
He officially retired at the end of the 1992 calendar year and took up post-retirement employment which ended in 1993. Josh had served the department for 36 years, plus 5 additional part time years as an emeritus professor.
Josh's research had centered on probability theory and stochastic processes. More recently he had turned his attention to the study of mathematical models in biology, studying the brain via neural networks with random connections. Five graduate students completed dissertations under his supervision.
Josh was devoted to teaching and curriculum development on both the undergraduate and graduate level, and wrote "The Green Book of Calculus" in 1972 for a course he developed here. He was the originator of the idea of the Wednesday Noon Talks and brought many lively and informative lectures to Van Vleck Hall from around campus.
His entire life he enjoyed painting and was exhibited at the Pyle Center in 2016.
UW Alumnus Song Sun (Ph.D., 2010, Xiu-Xiong Chen) has won a New Frontier Award from the Breakthrough Foundation for many groundbreaking contributions to complex differential geometry, including existence results for Kahler-Einstein metrics and connections with moduli questions and singularities. Song Sun currently is at UC-Berkeley.
Our own Leonardo Zepeda-Nunez was part of this new method to expand the theoretical limit on the complexity of simulations.
Computer simulations of waveforms are essential tools for researchers in many fields, from earth science and the energy industry to medical imaging. A new mathematical method developed by MIT researchers eliminates a theoretical limit on the complexity of the simulations these fields can create as they work with increasingly powerful supercomputers.
The Institute for Foundations of Data Science (IFDS), in an expanded partnership with the University of Washington, the University of California Santa Cruz and the University of Chicago, has been awarded a five-year $12.5 million grant from the NSF TRIPODS program, one of only two institutes nationwide to receive Phase II funding. Several Math faculty are affiliated with the IFDS, which fosters interdisciplinary collaboration in data science through weekly informal meetings, special interest groups, workshops and summer schools. The IFDS also supports a number of Math graduate students who benefit from mentoring by faculty outside the department. Sebastien Roch, co-PI on the grant, serves on the institute's executive committee.
