My InterestsI work on variational analysis and nonsmooth optimization, with a particular interest in semialgebraic optimization and variational properties of eigenvalues. My research is supported by National Science Foundation Grant DMS1613996. I am a SIAM Fellow. I am a CoEditor of Mathematical Programming A, an Associate Editor of Mathematics of Operations Research and SetValued Analysis, and a Council Member of the Mathematical Optimization Society. My research has been recognized by the 1995 Aisenstadt Prize, from the Canadian Centre de recherches mathematiques, the 2003 Lagrange Prize for Continuous Optimization from SIAM and the Mathematical Programming Society, and an SIAM Outstanding Paper Award in 2005. I was an Invited Speaker at the 2014 International Congress of Mathematicians in Seoul. I served as Director of ORIE from 2010 to 2013. I have also served on the editorial boards of the SIAM Journal on Optimization, the SIAM Journal on Matrix Analysis and Applications, SIAM Journal on Control and Optimization, and the MPS/SIAM Series on Optimization. I have served as Treasurer of Foundations of Computational Mathematics. My longtime friend, mentor, and coauthor of Convex Analysis and Nonlinear Optimization, Jon Borwein, passed away in 2016. I miss him. I updated these pages in January 2018.
