I am Sreeharsha, a computer science researcher interested in Distributed Systems. I am currently enrolled in the Computer Science PhD program at the University of Waterloo. I work with the Waterloo Advanced Systems Lab, advised by Prof. Samer Al-Kiswany.

I focus on research involving recent networking advances, network failure analysis, and data deduplication for cloud-based systems. I am currently working on improving content-defined data chunking techniques and enhancing security guarantees within deduplication systems.

Prior to this, I worked at AMD as a Design Engineer and have received my master's degree in computer science from the University of Waterloo.
