Benjamin Grimmer

Something went wrong I am a second year PhD student in Operations Research at Cornell University, where I am working with Jim Renegar and Damek Davis. However, I spent Fall 2017 at UC Berkeley as part of a Simons Institute program on continuous and discrete optimization. Prior to coming to Cornell, I completed a BS and MS of Computer Science at the Illinois Institute of Technology, where I worked on a variety of different projects with Professors Ioan Raicu, Gruia Calinescu and Sanjiv Kapoor.

In general, I am interested in the design and analysis of algorithms. My current research focuses on algorithms for continuous optimization problems where very little structure is assumed. In particular, I have recently been focused on the convergence analysis of subgradient methods for problems outside the scope of the traditional theory. I was awarded an NSF Fellowship in 2017 supporting this research.
