About me

Assistant Professor,

Computer Science Department,

 Stony Brook University

Office NCS 151

email: supartha @

Before November 2021, I was a postdoc with Anne Broadbent at the University of Ottawa and with Scott Aaronson at UT Austin. I received my PhD in computer science from the Centre for Quantum Technologies, National University of Singapore in Singapore, under the supervision of Hartmut Klauck

I obtained my masters from École Normale Supérieure de Cachan (ENS de Cachan) (thesis advisor: Iordanis Kerenidis) and from Chennai Mathematical Institute (CMI). (thesis advisor: Meena Mahajan).

News: Masters positions are available in quantum complexity theory. Contact me if you are interested. 


Interests: Quantum computing, Complexity theory, Quantum cryptography, Analysis of Boolean functions.

On the fine-grained query complexity of symmetric functions.
