Research
My research aims to improve the user experience, affordability, accessibility, and
privacy of networked
systems. My current research centers on building technologies for the developing world, using computational social science, machine learning, and causal
inference to develop approaches to combat the negative externalities of
technology (e.g., fake news, lack of data privacy), and design of architectures, protocols, and applications for
large-scale edge datacenters. I lead the Networks
and Systems Group (NSG) at LUMS.
