I’m a 5th year PhD student at University of Illinois at Urbana-Champaign advised by Prof. Radhika Mittal. I am broadly interested in Computer Networks. My recent research focuses on congestion control, rate enforcement and network resource management.

Previously, I got my Bachelors in Computer Science from LUMS, Pakistan where I worked with Prof. Ihsan Ayyub Qazi and Prof. Zafar Ayyub Qazi on web transcoding and video ABR algorithms.
