## About Me

I am a fifth-year PhD student in the BraQIIIT lab at IIIT-Delhi, where I am very fortunate to be advised by Prof. Debajyoti Bera. In the fall, I will be joining as a postdoc at the University of Latvia, Riga, where I will be hosted by Prof. Andris Ambainis.

## My research

My main area of research lies at the intersection of quantum computing and computational learning theory, and involves developing algorithms for discriminative and generative tasks under various noise models and proving theoretical bounds for convergence, generalization, and speedups.
