Stephen Becker is an associate professor of applied mathematics at the University of Colorado Boulder, with courtesy appointments in the Electrical, Computer and Energy Engineering and Computer Science departments. Previously he was a Herman Goldstine Postdoctoral fellow in Mathematical Sciences at IBM Research in Yorktown Heights, NY, and a postdoctoral fellow via the Fondation Sciences Mathématiques de Paris at Paris 6. He received his PhD in 2011 from Caltech under Emmanuel Candès, and bachelor’s degrees in math and physics from Wesleyan University.

Our group’s work has been recognized with the Beale Orchard-Hays prize given out every 3 years by the Mathematical Optimization Society. We are graciously funded by the DOE Office of Science’s ASCR, by a DOE funded MMICC center CHaRMNET, and by the National Science Foundation (NSF); and have previously been supported by Northrop Grumman, Bloomberg and by NVIDIA hardware grants.

Stephen is on the editorial boards at Transactions on Machine Learning Research and the SIAM Journal on Mathematics of Data Science (SIMODS); a technical editor for Mathematical Programming Computation; and a frequent meta-reviewer for NeurIPS, ICML, ICLR and AISTATS.

  • Switched to Jekyll for website

    Migrating the website to use jekyll instead of jem-doc. Jem-doc is now about 10 years old and not supported, and finally broke with some python 2 vs python 3 issues. This new jekyll website should display much better on phones.
