The optimization research group meets on a weekly basis to share and discuss current optimization research in the Applied Mathematics Department 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 and Noemi Petra and consist of graduate students, postdocs and faculty in the Applied Mathematics Department.

During Spring 2019 these meetings are held in the
