About
I am a postdoctoral researcher at TU Darmstadt (ENCRYPTO group, Prof. Thomas Schneider). I completed my PhD at the Indian Institute of Science (IISc), Bangalore under Prof. Arpita Patra. My work focuses on theoretical and practical aspects of cryptography, with an emphasis on privacy-preserving protocols, secure computation, zero-knowledge, and applied cryptographic primitives.
Currently: Postdoc at ENCRYPTO, TU Darmstadt.
Previously: PhD, IISc Bangalore.
