Research

My research interests are in computer networks and distributed systems and span datacenters and cloud computing, Internet censorship, mobile/wireless networks, and ICT for developing regions. My research goal is to design and build new architectures and protocols that improve the performance, robustness, and evolvability of networked systems. I lead the Networks and Systems Group (NSG) at LUMS.
