Research staff

Lawrence Cheng is a research fellow. His research interests lie in the area of wireless ad-hoc networks, sensor networks, P2P networks, distributed systems, and more. He joined the Systems and Network Research Group in Jan 2007, and is working on the SESAME project.
Piers O'Hanlon is a research fellow. His interests are in the creation and operation of real-time congestion controlled networked multimedia systems, over IPv4 and IPv6 networks. He has worked on the UCL multimedia tools providing various enhancements, support and new features. He is also involved with IPv6 based Grid and VoIP systems, and is a contributor to the IETF. He is currently managing the AVATS project, which is providing for support and development of the media tools.
Socrates Varakliotis is a research fellow. His research interests lie in the area of 3-D mesh coding and streaming of QoS-enabled wireframe animations over the Internet. In addition, he's interested in redundand code optimisations and rate control, and their interaction with three-dimensional adaptive graphics. He also investigates metrics that quantify the quality of streamed animations.

Research students

Anil Bawa-Cavia is a research student. He is working on the EPSRC project SCALE (Small Changes Lead To Large Effects): Changing Energy Costs in Transport and Location Policy.
Vasileios Giotsas is a research student. He is working on modelling communications and information networks, such as the Internet and online social media networks.
Nikola Gvozdiev is a research student.
Georgios Nikolaidis is a research student. He is currently working on interference in wireless networks and his research interests revolve around networks, especially wireless communications and routing, operating systems and distributed systems and algorithms.
Christopher Pluntke is a research student. He is working on scheduling algorithms for all-optical networks. He is jointly supervised by Damon Wischik and Polina Bayvel from the Electrical Engineering department. He is currently on an internship at Bell Labs.
Lynne Salameh is a research student.
Michael Rogers is a research student. He interested in censorship-resistant communication and unmanaged networks (eg peer-to-peer and ad hoc mobile networks). In networks with open membership and no central administrative authority, security involves questions of trust between participants, and performance relies on protocols that reward co-operative behaviour.
Jie Xiong is a research student. His main interests are in the cross layer design of wireless networks and in multi-antenna (antenna array) systems.
Astrit Zhushi is a research student.

Former students

Torsten Ackemann was a research student. His main interests are in area of peer-to-peer networks and other peer-oriented networks and distributed systems such as grids, overlay networks, and mobile ad-hoc networks. Specifically, he is interested in how to design these systems so as to maximize their flexibility, performance and reliability by providing incentives for cooperation between the nodes of the network. Torsten is also a member of the Software Systems Engineering Group, and is supervised by Dr. Wolfgang Emmerich.
Mohamed Ahmed is a research student. His interests lie broadly within AI and security. He is looking at pervasive computing environments and the uncertainties introduced by the increased scale, the heterogeneity of devices and services and mobility of users. Specifically his work focuses on adapting the traditional models of trust and assurance to be more dynamic and adaptive in prescribing rights to users and be more proactive in response to anomalies. He is involved in the MARS project, his PhD research is funded by the EPSRC through an Industrial Case with BTexact, and is supervised by Dr. Stephen Hailes.
Saleem Bhatti is a Professor at the School of Computer Science, University of St Andrews. Saleem holds a B.Eng.(Hons), in Electronic and Electrical Engineering, an M.Sc.(Distinction) in Data Communication Networks and Distributed Systems, and a Ph.D. in Computer Science, all from UCL.
