Satyabrat Rath

About

During my Ph.D., I worked on designing secure outsourcing protocols for verifiable computations under the guidance of Prof. R Jothi Ramalingam . After my Ph.D., I worked with Dr. R Kabaleeshwaran on secure post-quantum digital signature schemes from lattices. I am currently a Postdoctoral Fellow, working with Prof. Monosij Maitra at Department of Computer Science and Engineering, IIT Kharagpur.
