About

I am a second year Ph.D. student at Department of Computer Science, Georgetown University, where I am advised by Prof. Benjamin Ujcich and affiliated with SECLAB. Prior to joining Georgetown, I worked as a Research Assistant at the Department of Computer Science and Engineering, IIT-Hyderabad under the supervision of Prof. Praveen Tammana. I received my Bachelor’s degree from the Department of Computer Science and Engineering, Tezpur University, advised by Prof. Nityananda Sarma . My broad interests lie in the intersection of systems, software-defined networking (SDN), and programmable data planes (PDPs). In addition to my research interests in systems and software-defined networking (SDN), I have also developed a strong foundation in various technical skills. These include configuring hardware such as smartNICs (Netronome) and Tofino Switches (Intel). Overall, I believe that my technical skills, combined with my curiosity and passion for computer science, make me well-suited for a successful career in research and academia.
