Office: Room 307, CSE Main Building, IIT Kharagpur.
I work as a faculty in the CSE department at IIT Kharagpur. My research interests are broadly in the theory and applications of public-key cryptography with a focus on computing on encrypted/authenticated data and building tools to enable distributed trust.
Before joining IIT Kharagpur, I worked as a postdoc jointly with Eike Kiltz (at Ruhr-Universität Bochum) & Giulio Malavolta (at Max Planck Institute for Security and Privacy). Prior to that, I worked as a postdoc with Sebastian Faust (at TU Darmstadt). Earlier, I received a PhD in CSE from IIT Madras and then worked as a research staff at CCD@IITM. During PhD, I was very fortunate to be advised by Shweta Agrawal.
