Hi 👋! I'm a final-year Dual Degree student at IIT Madras, working with Prof Kaushik Mitra in the Computational Imaging Lab.
I've spent summers at IIIT Hyderabad and UIUC. In 2023, I worked with Prof P.J. Narayanan (IIITH), and in 2024, with Prof Yuxiong Wang (UIUC). For my Master's thesis, I'm collaborating with Prof Kaushik Mitra and Prof Aswin Sankaranarayanan (CMU) on imaging and graphics.
I'm applying for PhD programs this fall!

About Me

When I'm not working, I enjoy playing table tennis with my labmates or practicing the flute, a skill I recently picked up. I have a spiritual inclination and love visiting holy places of worship, finding peace. Admittedly, I also indulge in binge-watching YouTube, though it often comes with a tinge of regret later. Occasionally, I join my neighbors for a game of cricket. I am always open to discussions or collaborations in related areas—feel free to reach out to me via email.
