I now work at Oxford University's Oxford Internet Institue. I used to work in the Networks Research Group (also see here). I arrived at UCL a while back and was based at what was then called the MultiMedia Support and Communications Centre, now known as Media Resources, till 1998 when I came to the UCL Computer Science Department.
what

Currently I'm spending most of my time at Oxford on security and privacy issues in networks, though I do some private consulting work on IETF transport protocols, and some other work on conferencing systems, and robotic control systems.

The last project I worked on the at UCL was the EU Trilogy Project doing performance testing of Multipath TCP. Before that I was working on the EU GLOBAL project - integrating VOIP solutions with the Isabel conferencing system. I also continue to lecture on IPv6 (security, MobileIPv6, MLD etc) at various workshops as part of the EU 6DEPLOY project, and previously 6DISS.

Previously I managed the OMII-UK funded AVATS project - which provided support for the Media tools (VIC,RAT,UCL common lib) - most widely used in Advanced Collaborative Environments such as AccessGrid. Prior to this I managed the SUMOVER project which provided support and development of the media tools - integrating a number of enhancements, bringing the code into a common code base, and deploying the Trac and Subversion based code management system.

Previously I was working with IPv6 in a number of projects; The 6NET project was involved with building and testing an IPv6 research network across Europe, and also worked on the Grid. Before that I worked on 6WINIT which was deploying and testing Mobile applications on IPv6. The project was one of the first to test IPv6 over Ericsson's 3G research network in Stockholm (in 2002). I am currently cochair of the OGF IPv6 Working Group - though the group is now dormant.

Earlier I worked on Active Networks in the RADIOACTIVE and ANDROID projects. We were mainly concerned with application level active networks (alan) and policies. I was also involved with the COIAS and MECCANO projects - porting, testing and developing the Multimedia Mbone tools. Prior to this I worked on the ALAVIT project which involved testing and cataloguing desktop videoconferencing products - Both end systems and gateways/gatekeepers in context of H.323 and Mbone.

Back in MMSCC I worked on a number of projects; Before I left I was working on the ARIADNE project which is developing a distributed database of reuseable computer based teaching materials, with associated tools for developing courses and material. In parallel I was partially involved in the ASITIL project which involved setting up an ATM LAN for testing and some development of video server and teaching systems, with a view to implement smooth two-way integration between the digital network of desk-top computers, and analogue networks such as the UCL LIVE-NET network. The INSURRECT project, which involved developing and testing technology to do surgical teaching over digital (ATM and IP) videoconference links. Prior to that I worked on the MTS project under EU Framework IV developing remote teaching techniques for low cost teaching over satellite links.

I have maintained the RTP based videoconference tool (vic) since 1999 originally from Laurence Berkeley Laboratories, and worked on the other UCL Media tools, including the UCL common multimedia library.

I enjoy various things including travel - especially to weird places. If you're interested in staying in Lisbon, then then try one of these flats. Here's my brother Austen's Art site (which I put together).

I have been involved with the Dancemachine - A live interact multichannel Audio and Video Art installtion which debuted in Tate Britain and since has toured to Geneva and Dublin. The concept was conceived by Guy Baramotz, whilst I designed and built the core hardware and software.

See my problems and answers page (old) for awkward tech stuff that I've run into - basically timesinkers.
