CEO, Ammbr Research Labs


Dr. Arjuna Sathiaseelan is the CEO of the Ammbr Research Labs (part of the AmmbrTech group) and the Co-Founder of GAIUS Networks. Before moving to the industry, Dr Arjuna Sathiaseelan directed the Networking for Development (N4D Lab) at the Computer Laboratory, University of Cambridge. The research group conducted research on novel Internet architectures for improving and reducing the cost of Internet access. He founded and chaired the IRTF Global Access to the Internet for All (GAIA) research group and was a member of the Internet Research Steering Group (IRSG). He was in the Access Advisory Panel of the United Nations Foundation's $75 million Digital Impact Alliance (funded by the Melinda and Gates Foundation, USAID and SIDA). He is in the advisory board of Tresorio Hub focussed on green edge computing infrastructure, Ubuntu Power - an social enterprise focussed on providing affordable off grid energy and Internet to underserved communities and Ensemble- an social business incubator in Democratic Republic of Congo. He is also in the advisory board of the EU NETCOMMOMS project. He is a member of the Center for Science and Policy (CSaP). He is also a member of the Cambridge Big Data initiative as a principal investigator interested in big data for development and understanding the interplay between users, networks and data for development and humanitarian crisis.

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). He was awarded the Young Alumini Achiever Award from NIT Trichy (2016).

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 (, 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 efforts that could potentially change the Internet landscape to be more inclusive.

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 and TCP Congestion Window Validation (RFC 7661):
