Early life
Born in Singapore, Toh received his university education in the United Kingdom. He subsequently moved to live and work in the United States. He 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 in 1996 and his undergraduate EE degrees at the University of Manchester, Institute of Science and Technology in 1991.
Industry, Public Sector and Universities
Toh had served as Group CTO and Assistant Chief Executive. of Singapore's IDA - Infocomm Development Authority of Singapore, the country's telecom regulator, ICT policy maker, and infocomm technology implementor for the country of Singapore. IDA is equivalent to the U.S. Federal Communications Commission (FCC) coupled with National Institute of Standards and Technology and Lawrence Livermore National Laboratory. Toh is also interested in startups and ventures.
During the time from 2002-2004, he was the Director of Research, Communication Systems, at TRW Systems Corporation (now Northrop Grumman Inc) in Carson, California. After his PhD in 1996, he joined 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 as an engineer at Advanced Logic Research Computers, Archive Corporation, and served on the technology advisory board of Convergence Corporation (acquired by Amazon ).
In 2011, he was appointed the Tsing Hua Honor Chair Professor of Computer Science (Taiwan). He has also been 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. Earlier on, he was a tenured Chair Professor at the University of London (2004–2006) and on the faculty at University of California, Irvine and at Georgia Institute of Technology.
Inventions & Awards
Toh was as an IEEE Expert Lecturer of the IEEE Communications Society during the time from 2002–2003. He is also 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 15,000.
He is also an inventor. He invented Associativity-Based Routing and Wireless Mobile Ad Hoc Networks, and in real life, known as "Wi-Fi Ad-Hoc Mode". His first success of implementing Wi-Fi Ad-Hoc Mode was achieved in 1999 and published in mobile computing magazine at that time. In 2009, he challenged the "always-on" Internet model, claiming that the resulting energy burden globally is not sustainable. Instead, he advocated re-designing existing Internet architecture, routers, switches, servers and data centers. In 2011, he invented a method to identify witnesses during car accidents using a distributed information dissemination and data fusion approach.
He is an elected Fellow of the IEEE (FIEEE), a Fellow of the American Association for the Advancement of Science (FAAAS), Fellow of the British Computer Society (FBCS), Fellow of IEE (Institution of Electrical Engineers), Fellow of HKIE Hong Kong Institution of Engineers, Fellow of IITP (Institute of IT Professionals - formerly known as New Zealand Computer Society), Fellow of Cambridge Commonwealth Society, and Life Fellow of the Cambridge Philosophical Society, UK. He is a Chartered Engineer (UK) and Chartered IT Professional (CITP).
In 2005, IEEE awarded him 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, 1997) and "Ad Hoc Mobile Wireless Networks" (Prentice Hall Best Seller, 2001). In 2009, IET awarded him the John Ambrose Fleming Medal (IET Achievement Medals) in London.
