I am a computer systems researcher. My work builds modern systems and data infrastructure that are more reliable, efficient, and fast. My research spans storage, memory, and distributed systems, with an emphasis on building principled yet practical abstractions and designs that keep them reliable and fast.
I earned my PhD in computer systems from the University of Wisconsin-Madison. I spent two years as a postdoctoral researcher in the VMware Research Group. From Fall 2022, I have been an Assistant Professor in the Department of Computer Science at the University of Illinois Urbana-Champaign, where I co-lead the Distributed And Storage Systems Laboratory (DASSL).
Current Research Interests
Our group is currently focusing on a few connected areas:
- Real-time data infrastructure with a focus on applications that demand low latency.
- New fault-tolerant logging abstractions for modern applications.
- CXL memory systems for efficient and correct data sharing.
- Agent-first data infrastructure, a newer direction in which we are building new data abstractions and systems for AI agents.
I am always looking for self-motivated, hardworking, and creative PhD students. If you are interested in systems (memory, storage, distributed systems), please apply to the UIUC CS PhD program and mention my name in the application.

Teaching
I am passionate about teaching computer systems. Usually, I teach undergraduate operating systems (CS 423) in the Fall and a graduate-level storage systems (broadly construed) course in the Spring.
