I develop high-performance, scalable systems for big data and ML applications. My research advocates an application-oriented design principle for big data and ML systems: fully exploiting application-specific structures --- communication patterns, execution dependencies, ML model structures, etc. --- to suit application-specific performance demands. This principle has led to several scalable systems with theoretically sound scheduling algorithms tailored for different big data and ML applications. I received a Google Ph.D. Fellowship in systems and networking.

Biography: I am a PostDoc in the RISELab at UC Berkeley working with Prof. Ion Stoica. I received my Ph.D. from Department of Computer Science and Engineering, Hong Kong University of Science and Technology, where I worked with Prof. Kai Chen in System networkING (SING) research group.
