David Mackay

Also known as D Mackay, D. J. C. MacKay, D. J. C. Mackay, D. MacKay, D. Mackay

David MacKay was a physicist and machine-learning researcher whose work included Bayesian methods for artificial neural networks and information theory. He studied Natural Sciences at Trinity College, Cambridge, earned a PhD in Computation and Neural Systems at Caltech, and returned to Cambridge to lead its Inference Group. With David Ward, he designed Dasher, a 2002 language-model text-entry system; in 2003, he published Information Theory, Inference, and Learning Algorithms. He published Sustainable Energy – Without the Hot Air in 2008, served as the UK's chief scientific adviser on energy from 2009 to 2014, and became Cambridge's inaugural Regius Professor of Engineering in 2013. He was knighted in 2016 for services to scientific advice in government and science outreach, and died in 2016.

Timeline

  1. 1985–1992

    Trinity and a Caltech PhD

    At Trinity College, Cambridge, he studies Natural Sciences from 1985 and completes a PhD in Computation and Neural Systems at Caltech in Professor John Hopfield’s research group. In 1992, he returns to Cambridge as a Royal Society research fellow at Darwin College.

  2. 1992–2003

    Cambridge's Inference Group

    He becomes a lecturer in the Department of Physics in 1995, a reader in 1999 and professor of Natural Philosophy in 2003. At the department, he starts and leads the Inference Group.

  3. 2002

    Dasher predictive text

    In 2002, he and David Ward design Dasher, a text-entry system that uses a language model to make probable character sequences easier to select.

  4. 2003

    Bayesian neural networks and a textbook

    His research develops Bayesian methods for artificial neural networks. In 2003, he publishes Information Theory, Inference, and Learning Algorithms, a book that remains widely read in the field.

  5. 2008

    Sustainable Energy without the Hot Air

    In 2008, he publishes Sustainable Energy – Without the Hot Air to help people understand the numbers around sustainable energy.

  6. 2009–2014

    The 2050 energy calculator

    He serves as Chief Scientific Adviser to the Department of Energy and Climate Change from 2009 to 2014. At the department, he launches a 2050 calculator that lets users control energy demand and supply to reach the UK's 80% CO2 reduction target for 2050.

  7. 2009–2016

    Fellowship, a Regius chair and knighthood

    The Royal Society elects him a Fellow in 2009. Cambridge appoints him inaugural Regius Professor of Engineering in 2013, and the 2016 New Year Honours knight him for services to scientific advice in government and science outreach.

  8. 2016

    Death in 2016

    He dies in 2016.

  1. Of 216 AI researchers who entered public life, 83 held advisory seats and 58 took public rolesIncludes David Mackay. Of 216 AI researchers who entered public life, 83 held advisory seats and 58 took public roles. Another 97 people moved from public careers into AI organizations or research, with 62% of dated records starting from 2020 on.
  2. More people shaping AI studied at Massachusetts Institute of Technology than at any other institutionIncludes University of Cambridge. We estimate where the people shaping AI studied and where their careers led. Massachusetts Institute of Technology leads with 467 former students, including 291 recorded doctorates.
  3. The median h-index is 48 at universities and 14 at frontier AI labsIncludes University of Cambridge. The median h-index is 48 at universities and 14 at frontier AI labs. We compare publishing careers, recent citations, dual appointments and job moves across 2,420 university researchers and 308 frontier-lab researchers.
  4. Companies supply the most prior-work hires at 7 of the 9 frontier AI labsIncludes University of Cambridge. Our estimates of the organizations where 550 people worked directly before joining 9 frontier AI labs across 620 career transitions, comparing the main feeder organizations per lab.
