I am currently a PhD student in the
department of Computer & Information Science at University of Pennsylvania, affilated
with the Theory Research Group. I am very fortunate to have Sanjeev Khanna as my advisor.
Prior to my enrollment at Penn, I got my B.Sc. degree in Computer Engineering from department of Computer Engineering at
Sharif University of Technology, Iran.
My primary research interest is in theoretical foundations of big data analysis. This in particular includes sublinear algorithms and lower bounds in various models of computation for processing massive datasets such as streaming, distributed communication, and sublinear time algorithms. More broadly, I am also interested in communication complexity, online algorithms, and algorithmic game theory.
