I lead the Network Operations and Internet Security Lab.
Please contact me if you are interested in joining our research group.

Research area. My research focuses on networked computer systems, with a strong emphasis on (1) network operations; (2) network architecture and protocol design; (3) high performance (i.e., high availability, high throughput) wired and wireless networks; and (4) anti-censorship techniques and systems.

Goal. The primary goal of my research is to help network operators run their networks better, and to enable users of these networks to experience high availability and good end-to-end performance. I am strongly interested in tackling practical, real-world problems using a ``first principles'' approach, designing systems based on these principles, and implementing and deploying these systems in practice.

Approach. My research runs "from practice, to theory, back to practice". I look to the real world for inspiration and practical problems. I then design solutions to these problems that have provable properties and solid theoretical backing. Finally, I build and deploy real systems based on these solutions. This first principles approach means that I bring many "tools" to bear, from algorithms to economics to machine learning. I place a strong emphasis on transfer of these results back to practice: the resulting tools and algorithms have been adopted or applied in practice.
