I received the Ph.D. degree in Electrical Engineering from London University in 1967 and joined Bell Telephone Laboratories as a Member of Technical Staff in 1968. I retired from Bell Labs, Alcatel-Lucent, in January 2013.
During 1968-January 2013 I was at Bell Labs continuosly execpt for briefs sojourns. During the Fall semester of 1984 I was the Visiting McKay Professor at the University of California, Berkeley. I taught a graduate course in Parallel Processing. In 2003 I was the Albert Winsemius Professor at the Nanyang Technical University, Singapore.
In January 2013 I joined Columbia University as a Professor of Electrical Engineering at the Fu Foundation School of Engineering and Applied Sciences.
2008 - 2013
In 2008 the "old" Bell Labs of Lucent Technologies and the former Research & Innovations (R&I) organization of Alcatel merged to form the "new" Bell Labs of Alcatel-Lucent. I was appointed as Vice President in the newly created Chief Scientistís Office reporting to the Chief Scientist and responsible for Global Research Partnerships, University Relations and Technical Institutes. The Chief Scientistís Office has de facto responsibility to preserve and nurture the historical standards of technical excellence in Bell Labs.
Here are some achievements to which I and the team that I led made key contributions.
(i) The launch of Bell Labs Seoul in 2009. I was the Bell Labs executive who was given the responsibility to negotiate with the Seoul Metropolitan Government to create an industrial laboratory in Seoul in the image of Bell Labs in partnership with Korea University and with funding from the city government. This was the joint vision of then-Mayor (later President of the Republic of Korea), Myung-Bak Lee, and the President of Bell Labs. My multi-year task was to devise a research agenda of mutual interest, a plan and an execution strategy that required coordinating various organizations in Alcatel-Lucent, in particular the offices of the Intellectual Property division, the Chief Counsel and the Chief Financial Officer. Incidentally, Bell Labs Seoul has been a thriving research center.
(ii) Launch of the Center for Energy-Efficient Telecommunications (CEET) at the University of Melbourne in 2011. CEET is a partnership of the University of Melbourne, the Victoria state government, Alcatel-Lucentís APAC region and Bell Labs. CEETís funding is guaranteed for three years and it is hoped that CEET will be succeeded by a full-fledged Bell Labs in Melbourne. CEET has an active collaborative research agenda.
(iii) Launch of multi-year partnerships between Bell Labs and Koreaís ETRI and Kyongyon Universityís Gauchon Energy Research Institute in 2008-2009. The themes of the partnerships have been optical communications and smart grids. Supporting funds have come from Korean government and private sources; Bell Labs provides in-kind research support.
(iv) Assessment of Fundamental Science in Bell Labs, 2011 - 2012. Motivated to nurture and raise the quality and quantity of basic science in Bell Labs with its 10 locations and 800 researchers, the President of Bell Labs chartered the Chief Scientistís Office to, first, assess and, second, recommend actions. I have had a central role in this Bell Labs-wide activity. One specific outcome was the 1st Science Workshop in 2011. This has been followed by two more workshops. The total effect on the scientific life and culture of Bell Labs has been profoundly beneficial.
(v) Grand Challenge Challenge, 2008. I was "angel" to this initiative, which, soon after the merger into Bell Labs of two organizations with very different cultures and heritages, sought to develop and refine ideas for a Grand Challenge. Substantial funding was guaranteed for five years to develop and realize the ideas of the winning submission to a competition. I led a small team that organized an open, web-based, bottoms-up, inclusive process that was new to Bell Labs and generated considerable response.
(vi) Outreach, 2008-2011. I was instrumental in organizing scientific and technical workshops with participation from Bell Labs and its research partners at various locations around the globe. Our partners in the workshops have been Princeton University and Supelec (at Princeton and Supelec in 2008), INRIA (at Murray Hill and Rocquencourt, 2009), Singapore (2009), Auckland University (2009) and the Heinrich-Hertz Institute (at Berlin in 2011).
In 1999 I was appointed Director (later Vice President) of the Mathematical Sciences Center. In 2005 the center was augmented by the infusion of the Algorithms group from the Computer Science Center and renamed the Mathematical and Algorithmic Sciences Center, which I continued to head. The center was staffed by 35-50 members with doctorates from diverse disciplines.
The centerís roots were in the Mathematics Department of the Bell Telephone Laboratories, which was created in 1925 with Thornton Fry as its first head. Fry was succeeded by S.A. Schelkunoff, Hendrik Bode, Bob Prim, Henry Pollak, Ron Graham and Mike Garey. I succeeded Mike Garey. Among the many distinguished alumni of the center are Claude Shannon, John Tukey, Sydney Darlington, George Stibitz, Stephen Rice and David Slepian.
In 2005 on the occasion of the bicentennial of William Rowan Hamiltonís birth, I spoke at the Royal Irish Academy in Dublin on "Industrial Mathematics at Bell Labs: Past and Present". I based my talk around the contributions of Thornton Fry, John Tukey and Claude Shannon and their legacy.
During my tenure as head the work in the center was in five main areas:
As head of the Center, one of my priorities was to ensure rough parity between fundamental and applied research. I aimed for a mutually nurturing environment. I also actively supported the Center's ventures into new directions, notably optical networking, rapid provisioning at the optical and the IP layer, IP traffic measurements and modeling, representation in the IETF and supply chain networks. I also worked to develop close ties between the Center and Bell Labs' Advanced Technologies and the Business Units, notably Supply Chain Networks, Mobility Solutions, Lucent Worldwide Services and the Optical Networks Group. These rich interactions provided a continuous stream of new problems that challenged the researchers in the center. The solutions that grew from these collaborations impacted diverse organizations within the company. In the centerís annual performance evaluations of members of technical staff collaborations and collaborative results were specially recognized. Collaborations flourished and not surprisingly collaborations with the Math Center were greatly sought after. Also, the culture in the Center assured researchers that they could count on management support to take time to render field experiences into form that was accessible to their discipline-based communities, such as papers for journals and conferences,. The reputation of the center in universities and technical communities was high and consequently it was always able to hire the best and brightest.
