Varsha Bhat Kukkala

I am currently an assistant professor in the Department of Computer Science and Engineering at IIT Tirupati. Prior to this, I was a postdoctoral researcher at Indian Institute of Science (IISc), where I was hosted by Prof. Arpita Patra. I completed my PhD from the Department of Computer Science and Engineering at IIT Ropar, where I was advised by Prof. Sudarshan Iyengar.

I work in the area of secure Multi-Party Computation (MPC) and design privacy-preserving solutions to various real-world applications that demand a secure variant.
