Dinan Gunawardena is a Research Software Development Engineer in the Cambridge Systems and Networking research group at Microsoft Research Europe (since July 2001) based in Cambridge, U.K. Dinan has over 12 years experience working in the computer telecommunication and networking industry. His experience covers early work in ATM LAN technology through last mile wired and wireless access. Prior to joining Microsoft Research, Dinan worked for Adaptive Broadband Ltd as their System Architect in Radio Software and Networking. In addition to this role, he project managed the development of their point to point backhaul radio modem. Prior to taking on this task, Dinan held senior and lead technical positions within Adaptive's software development organisation. Dinan has also worked for Fujitsu DSL Solutions, Westell Inc. and Virata Corporation (in various senior software development / architecture positions). Dinan has published and presented several technical papers at various industry conferences and has been involved with several patent applications.
Dinan has also shipped research technology in Windows Vista (QoS extensions to LLTD - qWave). Dinan’s current technical interests are diverse ranging from Multi-media P2P technology (RedCarpet/ReWindTV), Core TCPIP congestion control (ECN/QoS/BaTS/4CP), Systems Security (System protection using HIPs) and recently Ad-hoc wireless research (Horizon) and Collaborative Filtering (TagBooster). Dinan has also spent time working on assignment in the Windows Networking division in Redmond, USA.
Dinan has a M.A. and B.A. in Computer Science from the University of Cambridge - Pembroke College (United Kingdom).
