🎓 Academic Background

Feb 2020 Ph.D. in Industrial Engineering at Northwestern
Jul 2015 M.Sc. in Industrial Engineering at Northwestern
May 2014 B.Tech. in Process Engineering at IITR

🔬 Research

I am interested in the theory and applications of robust optimization. More recently, I have also developed in interest in machine learning especially its theoretical aspects and how it can be used for scaling optimization algorithms.
