Demis Hassabis

Demis Hassabis was born in London, England, on July 27, 1976, the eldest of three children.⁠[1]

His father, Costas, is Greek Cypriot, with family roots in Famagusta; his mother, Angela, is Chinese Singaporean. He has said: “I have a Greek way of thinking.”⁠[2]

His mother worked at the British department store John Lewis, and his father had many jobs, including as a singer-songwriter; he has said neither parent was technical and described a “quite bohemian” upbringing in Finchley and Hendon in North London.⁠[3]

He began playing chess at four; at eight he used chess winnings to buy his first computer, a ZX Spectrum, and taught himself to program from books. He recalled: “Because I started playing chess when I was four, it really was very formative in how I think.”⁠[2]

From 1988 to 1990 he attended Queen Elizabeth’s School in Barnet, London; he reached chess master standard at 13, with a rating that made him the second-highest-rated under-14 player in the world, and captained England junior teams.⁠[4]

He finished his A-levels two years early and, at 17, coded the multi-million-selling simulation game Theme Park.⁠[5]

From 1993 to 1998 he was lead AI programmer and lead designer at Bullfrog Productions and Lionhead Studios in Guildford.⁠[6]

From 1994 to 1997 he studied computer science as an undergraduate at the University of Cambridge; he became the department’s first alumnus to receive a Nobel Prize. In 2018 the university established a DeepMind Chair of Machine Learning funded by a benefaction from his company.⁠[7]

In 1998 he founded the London game developer Elixir Studios, which released Republic: The Revolution (2003) and Evil Genius (2004).⁠[8]

He won the Pentamind world games championship a record five times before retiring from competitive play in 2003.⁠[4]

In April 2005 Elixir Studios announced it was ceasing day-to-day operations and selling its remaining assets and IP. As founder and chairman, he said: “today’s games industry no longer has room for small independent developers.”⁠[9]

He then returned to academia and completed a PhD in cognitive neuroscience at University College London (UCL) in 2009, supervised by Eleanor Maguire with Geraint Rees as secondary supervisor; he continued as a postdoctoral researcher at UCL’s Gatsby Computational Neuroscience Unit.⁠[10]

In 2007 he published a paper in PNAS with Dharshan Kumaran, Seralynne Vann and Eleanor Maguire showing that amnesic patients with bilateral hippocampal damage were markedly impaired at imagining new experiences, with imagined scenes lacking spatial coherence.⁠[11]

This research linking memory and imagination was named one of Science’s top ten breakthroughs of 2007.⁠[12]

From 2009 to 2010 he held a Sir Henry Wellcome postdoctoral fellowship spanning the Gatsby Unit at UCL, the McGovern Institute at MIT and HarvardHarvard UniversityHarvard University is a private research university in Massachusetts, established by the Massachusetts Bay Colony legislature in 1636 and named in 1639 for early benefactor John Harvard.

He said after the deal that he had no plans to leave London, where he lived with his wife, a molecular biologist, and two young sons.⁠[4]

In 2014 he received the Royal Society’s Mullard Award.⁠[12]

In October 2015 DeepMind’s Go program AlphaGo played its first game against three-time European champion Fan Hui; in March 2016 it beat Lee Sedol 4–1 in Seoul, South Korea, in a match watched by more than 200 million people, earning a 9 dan professional ranking.⁠[15]

DeepMind’s DQN system learned to play games on the Atari 2600 console: the team trained separate agents for 50 different games, each receiving only raw screen pixels and the score, with no prior knowledge of the rules.⁠[16]

In 2017 he was elected a Fellow of the Royal Academy of Engineering, and he was named to the Time 100 list in 2017 and 2025; he is also a Fellow of the Royal Society.⁠[17]

That year he was appointed CBE for services to science and technology.⁠[13]

With David SilverDavid SilverDavid Silver is a computer scientist who led reinforcement learning research at DeepMind for many years, heading the AlphaGo, AlphaGo Zero and AlphaZero projects and co-leading AlphaStar. A professor at University College London and Fellow of the Royal Society, he left Google DeepMind in 2026 to focus on Ineffable Intelligence, the company he founded.Open the full entry and colleagues he published the full evaluation of AlphaZero in Science: in 1,000 chess games against Stockfish it won 155 and lost six, it won 91.2% of shogi games against Elmo, and 61% of Go games against AlphaGo Zero.⁠[18]

In the CASP14 assessment AlphaFold achieved a median score of 92.4 GDT across all targets and 87.0 on the hardest free-modelling targets, and the CASP organisers recognised it as a solution to the challenge; CASP co-founder John Moult said: “We have been stuck on this one problem – how do proteins fold up – for nearly 50 years.”⁠[19]

In November 2021 Alphabet launched Isomorphic Labs, an AI drug-discovery company spun out of DeepMind and headquartered in London, founded and led by him as acting CEO while he also served as CEO of DeepMind; in May 2022 the company announced its first management team.⁠[20]

He and John Jumper received the 2023 Albert Lasker Basic Medical Research Award for leading the AlphaFold team and propelling protein structure prediction to unprecedented accuracy and speed.⁠[25]

Google released the Gemini family of models: Nano, small enough to run on a smartphone; Pro, which powered Bard from that day; and Ultra, due to reach products the following year. Google said Gemini scored 90.0% on the MMLU test, making it the first LLM to perform better than human experts on it. He presented the model together with Sundar Pichai.⁠[26]

The King conferred on him the honour of Knighthood as a Knight Bachelor, “For services to Artificial Intelligence.”⁠[27]

Google DeepMind and Isomorphic Labs published a paper in Nature introducing AlphaFold 3, a model for the interactions between proteins and other molecules that they said was 50% more accurate than existing methods; most of its features were made freely available for scientific use through the newly launched AlphaFold Server.⁠[28]

He and John Jumper were awarded the 2024 Nobel Prize in Chemistry “for protein structure prediction,” splitting half of the prize, with the other half going to David Baker; both were at Google DeepMind in London at the time.⁠[29]

He said: “Receiving the Nobel Prize is the honour of a lifetime,” noting that AlphaFold’s predictions had given more than 2 million scientists and researchers in 190 countries a tool for discovery.⁠[30]

Google DeepMind announced that an advanced version of Gemini Deep Think solved five of the six problems at the 2025 International Mathematical Olympiad within the 4.5-hour limit, scoring 35 of 42 points, a gold-medal score.⁠[31]
