Hi! I'm Soujanya Ponnapalli

Ph.D. Student

Research: Storage and Distributed Systems

About Me

At the University of Texas at Austin, I am advised by Prof. Vijay Chidambaram and am 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 my contributions to Sports and Cultural activities at the institute.
