Chai Keong Toh (a.k.a. C.K. Toh) is an engineer, professor, industry tech executive and thought leader. Toh has performed pioneering research on wireless ad hoc networks, mobile computing, Internet Protocols, and Multimedia for over two decades (20 years).

Background

Born in Singapore, he received his university education in the United Kingdom. He subsequently moved to live and work in the United States. Toh studied at King’s College, Cambridge under a Cambridge Commonwealth Trust Scholarship and received his Ph.D. in Computer Science from University of Cambridge, UK (1993–1996) and his undergraduate EE degrees at the University of Manchester Institute of Science and Technology (1989–1991) and Singapore Polytechnic (1983–1986).

Industry, Public Sector and Universities

Toh had served as Group CTO and Assistant Chief Executive of Singapore's IDA - Infocomm Development Authority, the country's telecom regulator, ICT policy maker, and infocomm technology implementor for the country of Singapore. IDA is equivalent to the U.S. FCC coupled with NIST and Lawrence Livermore Labs. Toh is also interested in startups and ventures.

Since 2011, Toh has been a Tsing Hua Honor Chair Professor of Computer Science (Taiwan). He is also an Honorary Professor at the University of Hong Kong, China (2004–2009), Honorary Professor at the University of Essex, UK (2013-2015), Honorary Professor at the University of Haute Alsace, FRANCE (2013), and Advisory Professor of Computer Science at Technical University of Valencia, SPAIN (since 2006). He had held several visiting professorships/appointments at YALE, Princeton, Stanford, Royal Institute of Technology (Sweden), EPFL Switzerland, Mid-Sweden University, Osaka University, National Taiwan University, KNU Korea, etc.

He was a tenured Chair Professor at the University of London (2004–2006) and was the Director of Research, Communication Systems, at TRW Systems Corporation (now Northrop Grumman Inc.,) in California, USA (2002–2004). Earlier on, he was on the faculty of University of California Irvine and Georgia Institute of Technology (1998–2001). He had worked at Hughes Research Laboratories in Malibu, California. At Hughes, he co-led the DARPA TTO DAMAN (Deployable and Adaptive Mobile Ad Hoc Networks) Program. Earlier on, he worked at Archive Corporation (a storage company acquired by Connor Peripherals), and Advance Logic Research Computers (acquired by Gateway Computers).

He has served on the technology advisory board of Convergence Corporation (acquired by Amazon).

Innovations and awards

Toh was an IEEE Expert Lecturer of the IEEE Communications Society (2002–2003). He is listed among the top 20 authors in Wireless/Mobile Networks in the world by THOMSON Essential Science Indicators (ESI) for technical papers published from 1995 to 2005. His GoogleScholar.com and Harzing.com Publish or Perish total citation exceeds 14,000.^[1]

Toh is also an inventor. He invented Associativity-Based Routing and Wireless Mobile Ad Hoc Networks, and in real life, known as "WiFi Ad Hoc Mode". His first success of implementing WiFi Ad Hoc Mode was achieved in 1999^[2] and published in mobile computing magazine at that time. Toh also invented car-to-car communications and witness detection in the event of accidents, hazards on the roads. See patents. In 2009, he challenged the "always-on" Internet model, claiming that the resulting energy burden globally is not sustainable. Instead, he advocated for re-design of the existing Internet architecture, routers, switches, servers and data centers. He proposed the idea of an "on-demand global Internet" to strive for a greener Internet.^[3]

He is an elected Fellow of the IEEE (FIEEE),^[4] a Fellow of the American Association for the Advancement of Science (FAAAS),^[5] Fellow of the British Computer Society (FBCS), Fellow of IEE (Institution of Electrical Engineers),^[6] Fellow of HKIE Hong Kong Institution of Engineers, Fellow of IITP (Institute of IT Professionals - formerly known as New Zealand Computer Society),^[7] Fellow of Cambridge Commonwealth Society,^[8] and Life Fellow of the Cambridge Philosophical Society, UK.^[9] He is a Chartered Engineer (CEng) and Chartered IT Professional (CITP).

In 2005, Toh received the IEEE Institution Kiyo Tomiyasu Technical Field Award with the citation - "For pioneering contributions to communication protocols in ad hoc mobile wireless networks". He has undertaken research in wireless ad hoc networks since 1993 (while at Cambridge University) and had written two sole-authored pioneering books: "Wireless ATM & Ad Hoc Networks" (Kluwer, 1996) and "Ad Hoc Mobile Wireless Networks" (Prentice Hall Best Seller, 2001). In 2009, he received the John Ambrose Fleming Medal (IET Achievement Medals) in London.^[10]
