What I'm looking for

I seek a research or postdoctoral position in theoretical physics focused on quantum gravity, holography, and infrared structure, within a collaborative academic environment that supports rigorous theory, mentorship, and publishable research opportunities.

I am a theoretical physicist working at the interface of quantum gravity, holography, and infrared structure of quantum field theory. My research interests include asymptotic symmetries, infrared divergences, bulk emergence in AdS/CFT, and quantum black holes.

As a research assistant at the Raman Research Institute and a collaborator and visiting student at Chennai Mathematical Institute, I have worked on LSZ-type scattering in the presence of Coulomb phase divergences, celestial holography, and the derivation of soft graviton theorems from on-shell actions. I coauthored a paper published in Nuclear Physics B and have multiple preprints developing tools for subregion duality and extremality.

My MSc dissertation examined black hole thermodynamics and the information paradox, and I have completed projects at IISc on WZW black holes and on constructing holographic theories for asymptotically flat space. I have been awarded multi-term research assistantships and visiting studentships to pursue these problems and to collaborate with senior researchers.

I also bring experience training AI systems—generating complex math, physics, and coding prompts and evaluating responses—to improve model problem-solving. I seek collaborative research roles where I can tackle foundational theoretical problems, publish rigorously, and mentor or learn within strong academic teams.
