I am Sreeharsha, a computer science PhD student at the University of Waterloo, advised by Prof. Samer Al-Kiswany. My research spans distributed systems, focusing on enabling the next generation of data center workloads by targeting scheduling, low-latency online data storage, efficient offline storage, and system reliability.
During my PhD, I interned with the Liquid Graph database team at LinkedIn. Before this, I worked at AMD for a few years on CPU performance (including the Ryzen series!). I spent a few summers during my undergraduate studies interning at Philips and the Indian Institute of Science.
