Shishir Nagaraja is a Reader in Computer Security. He specialises in network security and privacy. Within network security, his interests lie in solving security and concurrency challenges in the programmable networks. He also has a track record of developing privacy-enhancing technologies including unobservable communication networks, location-anonymous cameras, and location-anonymous audio recorders. Previously, he was instrumental in discovering social malware attacks on Google and the Tibetan movement as well as uncovering ISP-level censorship practices across the world. He has published over 20 peer-reviewed conference and journal articles in these areas. Shishir's has led work funded by £2.34M from Government (UK, US, India), charities, research councils (DST, EPSRC), and industry. He is currently PI of several projects from UKIERI, and from UK National Centres PETRAS and REPHRAIN. Previously, as PI of the EPSRC RASE project he led an international team of researchers to secure control-plane architectures for programmable networks. Previously he was PI on several projects from DARPA, DHS, DRDO, GCHQ, and DCMS projects on Botnet and Malware detection. His work has attracted a Google Equipment Award and an IBM X10 Innovation Award. His work has also been supported by the CPNI and DCMS.

Shishir is concurrently Adjunct Professor at ECE, UIUC. He spent nearly a decade in industry before joining academics and holds several patents in trust and security. Dr. Nagaraja holds a Ph.D. from Cambridge University where he was supervised by Ross Anderson. His thesis developed a link between evolutionary game theory and the dynamics of attacks and defences on networks.
