Piyush Srivastava पीयूष श्रीवास्तव

In August 2014, I submitted my dissertation at UC Berkeley. Since September 2014, I am a postdoctoral scholar at the Center for the Mathematics of Information in the department of Computing and Mathematical Sciences at Caltech. I am broadly interested in randomized algorithms (and especially in connections between phase transitions and the computational complexity of counting and sampling problems). My research advisor at UC Berkeley was Alistair Sinclair.

Before coming to Berkeley, I did my undergraduate studies in computer science at IIT Kanpur.
