I am a 5th year Ph.D. student in the Department of Computer and Information Science at the University of
Pennsylvania supervised by Prof. Vincent Liu.
Before Penn, I sampled random experiences in various contexts
of networked systems.
My research interests are broadly in systems and networking. I am particularly drawn to the tangible, interdisciplinary nature of the domain, encompassing distributed systems, programming languages, computer architecture, machine learning, and control theory; thus, I am self-motivated to acquire knowledge with a problem-driven mindset. Recently, my interest has been around uncovering the potential of widespread underutilization through co-designing emerging applications, software, and hardware accelerators, driven by an internal vision toward zero-waste networked systems.
