My research interests centre on networked systems, particularly in the context of security and measurement. Currently, I am working on the design, scalability and applications of blockchains with George Danezis and Sarah Meiklejohn as part of the EU DECODE and EPSRC Glass Houses projects. I am a member of IC3 (Initiative for cryptocurrency and Contract) and The UCL Centre for Blockchain Technologies (CBT). I am also interested in measurement and characterization of IP liveness via active Internet scans. Another area of research is understanding online ecosystems, especially in the context of security and information control.
I received my Ph.D. degree (Characterization of Internet Censorship from Multiple Perspectives) from the University of Cambridge in 2017 under the supervision of Jon Crowcroft (and co-supervised by Steven Murdoch, Vern Paxson, and Ross Anderson) where I was an Honorary Cambridge Trust Scholar, and was awarded the Mary Bradburn Scholarship by the British Federation of Women Graduates for my research work. I maintain ties with ICSI (UC Berkeley), where I interned in 2012 and 2013, and made research contributions to NSF projects on developing empirical basis for censorship and socio-economic perspectives on Internet security. Previously I worked on Intrusion Detection Systems (Bro), and wrote an open-source software for botnet detection (BotFlex). I received my Master's degree in Computer and Communication Security from National University of Science and Technology, Pakistan in 2013 for which I was awarded the President's Gold Medal.
