Ravi has received the Presidential Early Career Award for Scientists and Engineers, is series editor of Springer’s Graduate Texts in Mathematics, and co-founded MathOverflow and the Proof School.

 
 Timothy Gowers 1998 Fields Medalist, and the Chaire de Combinatoire at the Collège de France. Timothy is a life fellow of Trinity College, Cambridge. He received the 2016 Sylvester Medal, was knighted in 2012, was elected to the Royal Society in 1999, and received the 1995 Prize of the European Mathematical Society.

 
 Geoffrey Irving Cofounder and Chief Scientist of Resolution, formerly Chief Scientist of the UK AI Security Institute. Geoffrey led alignment teams at DeepMind and OpenAI, co-led Google Brain’s N2Formal neural theorem proving, and worked on computational physics and geometry at D. E. Shaw Research and Pixar. He holds a PhD in computer science from Stanford.

 
 Paul Christiano Director of the Alignment Research Center, and advisor to the Center for AI Standards and Innovation. Paul formerly led language model alignment at OpenAI, was head of safety at the US AI Safety Institute, and was an initial trustee of Anthropic’s Long-Term Benefit Trust. In 2023 he joined the UK’s Frontier AI Taskforce advisory board, and was among TIME’s 100 Most Influential People in AI.

 
 Executive Director Andrew Critch Holds a 2013 Ph.D. in mathematics from UC Berkeley, applying algebraic geometry to machine learning models. Andrew spent five years as a research scientist at Berkeley’s Center for Human-Compatible AI, and continues there part-time. Prior to MAISI he co-founded theMultiplicity.ai, a platform for AI models supervising and correcting each other, and the Survival and Flourishing Fund.

 
 Chief Operating Officer Jake Ross Previously Chief Operating Officer of Encultured AI, where he began as Communications Manager. Jake is the founder of BelongTogether, a practice focused on organizational culture and institution-building, and co-author of the second edition of Everyday Bias (Bloomsbury, 2026), which examines how algorithmic systems reinforce human bias. He holds a Master of Applied Positive Psychology from the University of Pennsylvania.

 
 Board of Directors Arul Shankar Professor of Mathematics at the University of Toronto. Arul’s research is in arithmetic statistics, and joint with Manjul Bhargava, he has proved that the average rank of elliptic curves is finite, and that a
