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

From 2002 to 2004, Toh was the Director of Research,[2] 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.[3] 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[4]).

Since 2011, he has been appointed the Tsing Hua Honor Chair Professor of Computer Science (Taiwan).[5] He has also been an Honorary Professor at the University of Hong Kong,[6] China (2004–2009), Honorary Professor at the University of Essex,[7][8] UK (2013–2015), Honorary Professor at the University of Haute Alsace, FRANCE (2013), and Advisory Professor of Computer Science[9] at Technical University of Valencia, SPAIN. Earlier on, he was a tenured Chair Professor at the University of London (2004–2006)[10] and on the faculty at University of California, Irvine[11] and at Georgia Institute of Technology.

In 2014, Toh was appointed as Assistant Chief Executive (Engineering And Technology), a newly created position, of Infocomm Development Authority of Singapore (IDA) in 2014.[12][13] He will subsequently be the Chief Engineering & Technology Officer (CETO) of IDA.[1]

Inventions and awards

Toh was as an IEEE Expert Lecturer[14] of the IEEE Communications Society from 2002 to 2003. He is also listed among the top 20 authors[15] 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 20,000.[16]

Toh also invented Associativity-Based Routing and Wireless Mobile Ad Hoc Networks (Wi-Fi Ad-Hoc Mode).[17][18] His first successful implementation of Wi-Fi Ad-Hoc Mode was achieved in 1998 when he established a working wireless ad hoc network in Georgia, USA.[19][20][21] 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.[22] In 2011, he invented a method to identify witnesses during car accidents using a distributed information dissemination and data fusion approach.[18] In 2009, he introduced "signs that talk", transforming traffic signs into wireless digital forms[23]

He is an elected Fellow of the IEEE (FIEEE),[24] a Fellow of the American Association for the Advancement of Science (FAAAS),[25] Fellow of the British Computer Society (FBCS), Fellow of IEE (Institution of Electrical Engineers),[26] Fellow of HKIE Hong Kong Institution of Engineers, Fellow of IITP (Institute of IT Professionals - formerly known as New Zealand Computer Society),[27] Fellow of Cambridge Commonwealth Society,[28] and Life Fellow of the Cambridge Philosophical Society, UK.[29] He is a Chartered Engineer (UK) and Chartered IT Professional (CITP).

In 2005, IEEE awarded him the IEEE Institution Kiyo Tomiyasu Technical Field Award,[30] 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"[31] (Kluwer, 1997) and "Ad Hoc Mobile Wireless Networks"[32] (Prentice Hall Best Seller, 2001). In 2009, IET awarded him the John Ambrose Fleming Medal (IET Achievement Medals) in London.[33][34] In 2019, he was elected to The Royal Academy of Engineering, UK.[35]
