I am looking for an internship position of machine learning and optimization in summer 2019.

My research interest lies in optimization, machine learning, and control. With these combinations, I develop methods related to modelings and algorithms in pursuit that AI problems can be solved with scalable and robust methods with theoretical guarantees.
