Research Activities

String Theory nowadays is the leading candidate for Quantum Gravity. Exploring various aspects of the theory and in particular what it has to say about the quantum structure of space-time is what I have been working on in the past couple of years. I believe that Matrix Theory formulations for String/M-Theory is the appropriate route to pursue to gain a better understanding about the Quantum Space-Time.

Present Research Project at IPM

Quantum Structure of Space-Time Emerging from String Theory in the context of AdS/CFT Correspondence.
