I am a PhD Candidate in the Department of Computer Science at the University of Toronto. I am a member of the Computer Systems and Networks group, and my advisor is Professor Bianca Schroeder.

I started as a Performance Analyst Engineer at NetApp in September 2022!

My research interests include the design and implementation of computer systems, especially storage and file systems, and distributed systems. My current research focuses on the reliability aspect of systems, along with their performance characteristics.
