I am an assistant professor in the Department of Industrial and Operations Engineering at the University of Michigan. I am also affiliated with Michigan Institute for Computational Discovery and Engineering (MICDE), Michigan Institute for Data Science (MIDAS), and Controls Group.

My research focuses on developing large-scale computational and statistical methods for structured problems. In particular, I develop new techniques in optimization, machine learning, and control to solve massive-scale and data-driven problems that stem from real-world applications.

 

 

I received my M.Sc. and Ph.D. degrees in Industrial Engineering and Operations Research from the University of California, Berkeley. I also received a M.Sc. degree in Electrical Engineering from the Columbia University, and a B.Sc. degree in Electrical Engineering from the Sharif University of Technology.
