I am a Ph.D. student at the University of Washington, Seattle working with and advised by Prof. Kurtis Heimerl and Prof. Richard Anderson at the intersection of the Systems/Networks and ICTD Lab. Broadly I work on practical ways to distributing trust in todays heavily trusted societal scale infrastructure. Some of these efforts include decoupling trust in 4G/5G telecom infrastructure, building high throughput payment networks, and infrastructure for Internet privacy. I have been fortunate to be supported by the Gaetano Borriello Endowed Fellowship For Change.

I am the TA for CSE 550: Computer Systems taught by Prof. Kurtis Heimerl in Fall 2020.

During Summer 2020, I spent my time as a Technology/Cryptography Research Intern with Nick Sullivan, Dr. Chris Wood, Dr. Marwan Fayed and many incredible people at Cloudflare Research where I worked on improving the security and privacy of DNS protocols with Oblivious DNS Over HTTPS and web performance using connection coalescing.

Before joining graduate school at UW for my Ph.D. I was as a Research Fellow at the Microsoft Research India lab (MSRI) advised by Dr. Bill Thies & Dr. Colin Scott in the Technology for Emerging Markets (TEM) group where I also worked closely with Dr. Indrani Medhi-Thies. In my work at the lab focused on systems and security, I was advised by Dr. Muthian Sivathanu & Dr. Satya Lokam. Prior to joining Microsoft Research, I worked as a software engineer (2016) and as an intern (2015) at Microsoft India Development Centre.

I pursued my undergraduate degree in Computer Science and Engineering at National Institute of Technology, Warangal '16 and a Technology Entrepreneurship and Product Design programme from Indian School of Business '16. My undergraduate project in route optimization was advised by Prof. K. Ramesh from the Department of Computer Science and Engineering, and the IEEE EPICS project on e-Governance and citizen complaint management advised by Prof. Lokam Anjaneyulu from the Department of Electronics and Communication Engineering. I was also advised by Prof. D.V.L.N. Somayajulu from the Department of Computer Science and Engineering.
