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 (now known as ENS Paris Saclay) (thesis advisor: Iordanis Kerenidis) and from Chennai Mathematical Institute (CMI). (thesis advisor: Meena Mahajan).

News: I am actively looking for masters students to work on quantum complexity theory. Write to 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.
