Hi! I'm Soujanya Ponnapalli

Ph.D. Student
Department of Computer Science
University of Texas at Austin
Research: Storage and Distributed Systems

About Me

At the University of Texas at Austin, I am advised by Prof. Vijay Chidambaram and a part of the Systems and Storage Lab. Broadly, my research interests are in and around distributed storage systems. My work primarily focuses on building I/O efficient storage systems for emerging technologies like Blockchains and Persistent Memory. Before grad school, I completed my Bachelors with Honors in Computer Science and Engineering from International Institute of Information Technology Hyderabad (IIIT-H). I received the best all-rounder gold medal for excelling in academics and extra-curriculars.
