Prashanth Raman

I am a postdoctoral researcher in theoretical high-energy physics at the Max Planck Institute for Physics in Munich, where I work with Johannes Henn. Previously, I was an IOE-IISc postdoctoral researcher at the Indian Institute of Science , working with Aninda Sinha. I completed my doctoral studies at the Institute of Mathematical Sciences , Chennai, under the supervision of Nemani Suryanarayana and Alok Laddha.

My research interests include the amplitudes program, S-matrix and conformal bootstrap, AdS/CFT correspondence, and mathematical physics.
