Bio

Dr Arjuna Sathiaseelan is a Senior Research Associate at the Computer Laboratory, University of Cambridge. He leads the Networking for Development (N4D Lab). The lab conducts research in architecting multi-layer resource pooling Internet technologies to support new low-cost access methods that would enable low cost Internet connectivity to enable social inclusion. The cross-disciplinary nature of this initiative cross cutting Computer Science, Social Science, Economics, Law and Policy Research will help uncover the incentives and games that produce successful strategies for getting closer to 100% coverage of Internet access. He is the Chair of IRTF Global Access to the Internet for All (GAIA) research group and a member of the Internet Research Steering Group (IRSG).

His research interests also include architecting the Future Internet, enabling quad-play (voice, video, data, mobility) convergence and mobile systems especially inter-RAT mobility. He has co-authored and contributed to several Internet standards and drafts (IETF) and contributed to the DVB-RCS2 standardization at the ETSI TM-RCS.

In the past he was a Research Fellow  (Connected Digital Economy - Rural Digital Economy hub and Networking - School of Engineering) at University of Aberdeen. He was also an Associate with the Center for Sustainable International Development (CSID) at Aberdeen where he founded and convened the ICT4D group.

He was also the Chief Evangelist @ United Mobile Apps, India, where he helped the company raise one million dollars in venture capital funding.

Arjuna Sathiaseelan has a PhD in Networking from Kings College London (2005), MSc in Computing and Internet Systems from Kings College London (2001) and Bachelors in Computer Science and Engineering from NIT, Trichy, India (2000).

Key Contributions

2012-: Initiated the Networking for Development (N4D) lab at the Computer Laboratory. The research group conducts research on novel Internet architectures for improving and reducing the cost of Internet access. Also founded the Internet Research Task Force's (IRTF) "Global Access to the Internet for All (GAIA)" research group. This initiative brings together some of the major players (industry, academia and NGO) in networking and ICT for development (Google.org, NSRC, A4AI, Commonwealth Telecommunications Organisation etc) under one common umbrella to understand and scope out the challenges in providing universal access and to influence standardisation e fforts that could potentially change the Internet landscape to be more inclusive. Currently the Chair of the IETF GAIA Research Group with Co-chair Mat Ford (ISOC).

2010-2012: Contributed to the standardization efforts at ETSI TM-RCS on the Higher Layer Specification for DVB-RCS2 (QoS, MPLS and VLAN Support).

2006-: Influenced the standardization of several transport protocols to suit multimedia applications at the IETF (especially influenced the change to the core congestion control algorithm of TFRC (RFC5348) which obsoleted RFC 3448):
