 About me


I work on large-scale machine learning, especially latent variable probabilistic models. My approach is to bond theory and practice in machine learning by designing algorithms with theoretical guarantees that also work efficiently in practice and lead the state of the art. In particular, I am interested in modeling machine learning problems as optimization frameworks and designing algorithms that have efficient guarantees in high dimensions while outperforming existing methods.
I got my Ph.D. from department of Electrical Engineering at University of Southern California with a minor in Mathematics in August 2015. My Ph.D. advisers are Professor Edmond Jonckheere and Professor Anima Anandkumar, UC Irvine. Before joining USC, I received my B.Sc. and M.Sc. in Electrical Engineering from Sharif University of Technology, Tehran, Iran in 2007 and 2009 respectively.
