Henry Cohn

Henry Cohn is a professor in the Mathematics Department at the Massachusetts Institute of Technology. His research interests include discrete mathematics, with a focus on discrete geometry, coding theory, cryptography, combinatorics, computational number theory, and theoretical computer science. Cohn joined the MIT mathematics department as an adjunct professor from 2010 to 2025 and has been a professor since 2025. He received his Ph.D. from Harvard in 2000 under the supervision of Noam Elkies and has held research positions at Microsoft Research and the University of Washington. His academic career includes notable distinctions such as being named a Fellow of the AMS in 2015 and receiving the Levi L. Conant Prize in 2018.

Henry Cohn is a Professor of Mathematics at MIT, specializing in discrete mathematics. His research focuses on the mathematical structures underlying optimization and geometry, with applications in coding theory, combinatorics, and computational mathematics. Cohn's work includes significant contributions to sphere packing, lattice theory, and the analysis of random structures. He has explored the universal optimality of lattices, such as the Leech lattice, and developed novel approaches to problems in discrete geometry and combinatorics. His research also extends to algorithmic design and the study of sparse graph convergence, emphasizing the interplay between algebraic and probabilistic methods.
