About me


Welcome to my webpage! I am an Applied Cryptography Researcher. Currently I am an Assistant Professor at the School of Data Science, IISER Thiruvananthapuram.

I earned my Ph.D. in Computer Science, specializing in Searchable Encryption. My research focuses on secure and efficient solutions in secure cloud computing, data privacy, and encrypted graph analytics. I conduct both theoretical investigations and applied work, including prototype implementations using real-world datasets.

Beyond research, I enjoy teaching and have conducted courses in Programming, Data Structures, and Algorithms for Ph.D. students. I am enthusiastic about C and Python.

I do research in trending areas, focusing on improving data security and privacy using advanced cryptography. Besides searchable encryption, my current research interests include the foundations of blockchain, with a focus on Ethereum and its Layer-2 technologies. My secondary interest lies in Post-quantum Cryptography.
