Research interests

I am broadly interested in networked systems. I hope to make them work better, by designing faster networks, more robust and scalable services, and supporting richer functionalities. My research explores the application of techniques from communications, information, and coding theories to practical system design and prototyping on real systems. My current focus is on wireless and mobile systems, including flexible wireless protocols, and mobile edge computing. Here is my Google Scholar profile.
