Hi! I am CS PhD student at University of Waterloo starting September 2015. My advisors are David Jao and Michele Mosca.

I did my masters with the Theory Group in Department of Computer Science at University of Toronto advised by Vinod Vaikuntanathan, and then started my PhD with Charles Rackoff before "transferring" to Waterloo.

I spent the Summer of 2014 interning at Microsoft Research India.

I did my undergraduate in Computer Science and Engineering at College of Engineering, Guindy.
