I am an Assistant Professor in the Department of Computer Science at Johns Hopkins University. I work in computer systems, with a focus on hardware-software co-design, programmable networks and machine learning systems. Before joining Hopkins, I spent a year in the AMPLab/RISELab at UC Berkeley, working with Professor Ion Stoica. I received my PhD in the Department of Computer Science at Princeton University in June 2016, advised by Professor Jennifer Rexford. My research has won USENIX NSDI Best Paper Award (2018) and USENIX FAST Best Paper Award (2019).
