Optimization Research Group at UC Merced

The optimization research group meets on a weekly basis to share and discuss current optimization research in the Applied Mathematics Unit here at UC Merced. In particular we have bi-weekly seminar talks, where students and faculty present aspects of their research.
 
Our group meetings and seminar are led by Professors Roummel Marcia, Juan Meza and Noemi Petra and consist of graduate students, postdocs and faculty in the Applied Mathematics Unit.
 
During Fall 2017 these meetings are held in the SE1 298 on Thursdays from 10am-11am
