Jeremy Avigad
Jeremy Avigad is a Carnegie Mellon University researcher who works on formal methods and AI for mathematics. After mathematics degrees at Harvard and Berkeley, he joined CMU's Department of Philosophy in 1996. He coauthored Lean's 2015 system description, the ProofNet benchmark for formal mathematics in 2023, and ImProver for optimizing proofs with a language model agent in 2025. His 2022 book, “Mathematical Logic and Computation,” received a 2025 Shoenfield Prize. As of October 2026, he holds the Dean's Chair in Logic and Philosophy of Mathematics and directs the Hoskinson Center for Formal Mathematics and the Institute for Computer-Aided Reasoning in Mathematics.

Timeline
-
1989–1996
Mathematics degrees and Carnegie Mellon
He earns a BA in mathematics at Harvard College in 1989 and a mathematics PhD at the University of California, Berkeley, in 1995. After a postdoctoral appointment at the University of Michigan in 1995, he joins Carnegie Mellon University's Department of Philosophy in 1996.

2004
Checking the prime number theorem
In 2004, he and students at Carnegie Mellon complete a formally verified proof of the Hadamard–de la Vallée Poussin prime number theorem.
-
2015
The Lean theorem prover
In 2015, he coauthors “The Lean Theorem Prover (System Description)” with Leonardo de Moura, Soonho Kong, Floris van Doorn and Jakob von Raumer. It describes Lean, an open-source theorem prover under development at Microsoft Research and Carnegie Mellon, designed to support interactive proofs and automated methods.

September 2021
Hoskinson Center announcement
In September 2021, Carnegie Mellon announces the Hoskinson Center for Formal Mathematics, with Avigad set to lead it. The center supports Lean's mathematical library, tools for translating mathematical statements into formal language, and educational resources.
-
2022
Mathematical Logic and Computation
In 2022, Cambridge University Press publishes his book “Mathematical Logic and Computation.” It covers proof theory, model theory, computability and axiomatic foundations, with an emphasis on logic's uses in computer science.
-
2023
ProofNet for undergraduate mathematics
In 2023, he coauthors ProofNet, a benchmark for automatically translating mathematics into formal language and proving undergraduate mathematics. Its 371 examples pair theorem statements in Lean 3 with statements and proofs in natural language.
-
2025
ImProver for proof optimization
At the International Conference on Learning Representations in 2025, he coauthors ImProver with Riyaz Ahuja, Prasad Tetali and Sean Welleck. The language model agent rewrites Lean proofs to improve user-defined measures, such as length and declarative structure.
-
2025
A Shoenfield book prize
In 2025, he receives a Shoenfield Prize from the Association for Symbolic Logic for “Mathematical Logic and Computation.”
-
August 2025
Directing ICARM
In August 2025, he directs the new Institute for Computer-Aided Reasoning in Mathematics at Carnegie Mellon. Supported by the National Science Foundation and the Simons Foundation, the institute brings together AI, formal methods and automated reasoning to support mathematical research.
-
As of October 2026
Dean's Chair at Carnegie Mellon
As of October 2026, he holds the Dean's Chair in Logic and Philosophy of Mathematics in Carnegie Mellon's Department of Philosophy and Department of Mathematical Sciences. He directs the Hoskinson Center for Formal Mathematics and ICARM, and his research focuses on formal methods and AI for mathematics.
