About

I am a senior undergraduate student at the Department of Computer Science & Engineering at IIT Delhi. I also spent a semester at the Faculty of Mathematics at the University of Waterloo. I have worked on quantum-inspired classical algorithms and large scale data clustering at IIT Delhi advised by Ragesh Jaiswal and Rajendra Kumar, self supervised learning at Wadhwani AI hosted by Makarand Tapaswi, applied statistical learning at Atlas Research and quantum cryptographic primitives at the Computer Science Group of Center for Quantum Technologies hosted by Rahul Jain.

I spent my high school years studying physics. Aside from technical research, I am a percussionist with a particular interest in Indian classical instruments. I also spend scattered spans of time learning about language, religion, philosophy, natural sciences and anthropology. I frequently write on my personal blog and research blog.

Research Interests

Broadly speaking, I am interested in the study of the world from a theoretical perspective. Specific interests, which tend to grow as time goes on include data clustering, quantum computing, statistical learning and algorithm design for modern information processing.
