I am a PhD gradduate student at University of Toronto , and I am fortunate to be supervised by Natalie Enright Jerger.
Generally, I am interested in solving problems relating to software infrastructure and heterogeneous hardware in data centers, including cloud systems, machine learning systems, and agentic systems.
I worked as a Reserch Intern at Microsoft Research.
