I am a senior researcher at Microsoft Research Redmond and the Office of the CTO, Azure for Operators. I did my Ph.D. in Computer Science at the University of Pennsylvania, advised by Prof. Vincent Liu. Before Penn, I sampled random experiences in various contexts of networked systems.

My interests are broadly in systems and networking, and I am drawn to the tangible, interdisciplinary nature of the domain. 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.
