Who Is Demis Hassabis, Chair of Google DeepMind?

Demis Hassabis is the chair of Google DeepMind, chief scientist of Alphabet, and founder and chief executive officer (CEO) of Isomorphic Labs.

At Layer3Labs, we build artificial intelligence (AI) agents for business workflows, so we follow leadership changes at the labs that build frontier models.

On August 5, 2026, Hassabis handed day-to-day management of Google DeepMind, which he had led since co-founding DeepMind in 2010, to Koray Kavukcuoglu. He now works with Sundar Pichai on artificial general intelligence (AGI) strategy and is leaning into his role at Isomorphic Labs.

Where Demis Hassabis Is Now

Demis Hassabis no longer runs the day-to-day operations of Google DeepMind. On August 5, 2026, Google announced that Koray Kavukcuoglu, now senior vice president (SVP) of Google DeepMind reporting to Sundar Pichai, would take over day-to-day running. Hassabis became Chair of Google DeepMind and Chief Scientist of Alphabet, and he continues to lead Isomorphic Labs as CEO.

Fortune reported that Alphabet shares fell around 5% following the announcement. Hassabis took the Alphabet chief scientist title as Jeff Dean left Google to co-found Discovery Loop, a transition detailed in our profile on Jeff Dean.

Executive Reorganization at Google DeepMind

The leadership reorganization announced on August 5, 2026, separated day-to-day running of Google DeepMind from Hassabis's new AGI strategy role. In a message to staff, Hassabis stated that "now is the right time for me to hand over my day-to-day operational responsibilities at GDM." Sundar Pichai described the move as "a role that allows him to put his full attention on actively shaping the future of AGI."

Koray Kavukcuoglu, previously Google DeepMind's chief technology officer (CTO) and Google's chief AI architect, became Senior Vice President (SVP) of Google DeepMind reporting to Sundar Pichai. As reported by Fortune, Kavukcuoglu does not hold a stand-alone CEO title. Kavukcuoglu oversees Gemini model development, frontier AI research, and the Gemini application and developer teams.

In his farewell note as CEO, Hassabis cited the Gemini application reaching over 950 million monthly users and named Gemini 4 among upcoming models. Teams evaluating these systems can consult our guides on how to use Gemini and our Gemini 3.1 Pro review.

Video Game Engineering and Design

Before entering academic neuroscience or artificial intelligence research, Demis Hassabis worked as a video game programmer and studio founder. According to his biographical record on Wikipedia, he achieved chess master standard as a child with an Elo rating of 2300, and later won the Pentamind world championship at the Mind Sports Olympiad five times between 1998 and 2003.

As a teenager, Hassabis co-designed and lead-programmed the 1994 game Theme Park with Peter Molyneux at Bullfrog Productions. Theme Park sold several million copies.

Hassabis completed the Computer Science Tripos at Queens' College, Cambridge, graduating in 1997 with a double first. He then worked as lead AI programmer on Black & White at Lionhead Studios and founded the London games developer Elixir Studios in 1998. Hassabis served as executive designer on Republic: The Revolution and Evil Genius until Elixir Studios closed in 2005.

Cognitive Neuroscience and Memory Research

Demis Hassabis then moved into cognitive neuroscience, where his research focused on memory and imagination. He earned a PhD in cognitive neuroscience from University College London (UCL) Queen Square Institute of Neurology in 2009 under the supervision of Eleanor Maguire.

His research showed that patients with damage to the hippocampus could not imagine new experiences. The work linked memory and imagination, and the journal Science listed it among the top 10 scientific breakthroughs of 2007.

Hassabis completed postdoctoral research at the Massachusetts Institute of Technology (MIT) and Harvard University before securing a Henry Wellcome fellowship at the UCL Gatsby Computational Neuroscience Unit. At the Gatsby Unit, Hassabis met future DeepMind co-founder Shane Legg.

Founding and Acquisition of DeepMind

Demis Hassabis co-founded DeepMind in 2010 alongside Shane Legg and Mustafa Suleyman. DeepMind's stated mission was to "solve intelligence" and use intelligence "to solve everything else." Hassabis served as chief executive officer from its creation through August 2026.

Google acquired DeepMind in 2014, reportedly for between $400 million and $650 million, according to CNBC, as published by NBC Miami. DeepMind drew worldwide attention with AlphaGo. According to DeepMind's research records, AlphaGo defeated European champion Fan Hui 5-0 in October 2015 before beating Go champion Lee Sedol 4-1 in Seoul in March 2016, a match watched by more than 200 million people.

In April 2023, Google merged DeepMind with the Brain team from Google Research to form Google DeepMind, appointing Hassabis as CEO to lead general AI development as outlined on the Google Blog. On December 6, 2023, Pichai and Hassabis jointly announced Gemini 1.0 in Ultra, Pro, and Nano sizes on Google's blog, describing Gemini as the first realization of the vision behind forming Google DeepMind.

Protein Folding and the 2024 Nobel Prize

The 2024 Nobel Prize in Chemistry was awarded for work on protein design and protein structure prediction. As recorded by the Nobel Foundation, one half of the prize went to David Baker for computational protein design, and the other half was awarded jointly to Demis Hassabis and John Jumper for protein structure prediction.

The Nobel committee cited the AlphaFold2 system developed in 2020 by Hassabis and Jumper, stating in their press release that the model solved a 50-year-old challenge in biology. AlphaFold had demonstrated its predictive accuracy at the CASP14 competition in November 2020 by reaching a median score of 92.4 Global Distance Test (GDT) across all targets, as documented on the DeepMind blog. Hassabis received a one-fourth share of the prize with his official affiliation listed as Google DeepMind, London, on his Nobel facts page.

On May 8, 2024, Google DeepMind and Isomorphic Labs introduced AlphaFold 3, predicting interactions across proteins, DNA, RNA, and ligands, and released the model weights for academic use in November 2024 as detailed on the Google Technology Blog. Hassabis was appointed a Commander of the Most Excellent Order of the British Empire (CBE) in 2017 and was knighted in 2024 for his work in artificial intelligence.

Commercial Drug Discovery at Isomorphic Labs

Isomorphic Labs is an Alphabet company that applies AI to drug design. Alphabet announced the company on November 4, 2021, spinning it out of DeepMind under Hassabis's leadership, as covered by TechCrunch. Hassabis continues to serve as founder and chief executive officer of Isomorphic Labs, whose team page lists him as Sir Demis Hassabis.

In his August 2026 note to Google DeepMind staff, Hassabis wrote that he would lean into his role at Isomorphic Labs, reiterating his conviction that the primary application of AI should be to improve human health. Our Isomorphic Labs explainer covers how the company works.

In May 2026, Isomorphic Labs raised $2.1 billion in Series B funding led by Thrive Capital, according to an Isomorphic Labs press release. Hassabis called the round "a massive vote of confidence" in Isomorphic's "AI-first approach to drug design and development."

Definitions and Forecasts for Artificial General Intelligence

In a March 2025 interview reported by NBC News, Hassabis stated that AGI is "a system that's able to exhibit all the complicated capabilities that humans can," forecasting that those capabilities would start to emerge over the following five to ten years.

In his August 2026 note to Google DeepMind staff, Hassabis wrote that he has worked toward AGI his whole life and now feels "it is close at hand." In the accompanying announcement, Sundar Pichai wrote: "Demis has described us as standing in the foothills of the singularity."
