About Me [CV]
I started my Ph.D. at UIUC in 2023. I am honored to be advised by Prof. Ram Alagappan and Prof. Aishwarya Ganesan. My broad area of interest is operating systems, distributed systems, and storage systems. These days I am looking into disaggregated memory and shared logs.
Before joining UIUC as a Ph.D., I finished my undergraduate also at UIUC working with Prof. Indranil Gupta, and master’s degree at CMU with Prof. Rashmi Vinayak.
