My research interest is primarily on continuous optimization, with applications to different scientific areas, including molecular conformation, quantum information, hybrid control systems and computer program verification.
I completed my Ph.D. in Fall 2013, under the supervision of Professor Henry Wolkowicz. I worked as a research associate, under the supervision of Professor Sriram Sankaranarayanan.

Here is my CV and my resume.
