Research

My research aims to improve the performance, robustness, and transparency of networked systems. My current research centers on networks protocols, architectures, and algorithms for large-scale datacenters, measuring Internet censorship and information controls, and building technologies for the developing world. I lead the Networks and Systems Group (NSG) at LUMS.
