Jeremy Hahn

Jeremy Hahn is an Associate Professor of Mathematics at the Massachusetts Institute of Technology, affiliated with the MATH department. His research focuses on algebraic topology and homotopy theory, particularly structured ring spectra. Hahn joined the Mathematics faculty as an Assistant Professor in July 2021 and was promoted to Associate Professor in July 2025. He earned a bachelor's degree in mathematics from MIT in 2013 and a PhD from Harvard University in 2018. Hahn's work includes equivariant chromatic homotopy theory, the classification of high dimensional manifolds, and the redshift conjectures in algebraic K-theory. He recently offered a new proof of the Segal conjecture and showed the real orientations of Lubin–Tate spectra.

Jeremy Hahn is a researcher at the Massachusetts Institute of Technology, specializing in algebraic topology, homotopy theory, and higher algebra. His work explores advanced topics such as topological cyclic homology, Lubin–Tate spectra, and real orientations. Hahn's research also delves into the structure of ring spectra, multiplicative properties of complex bordism, and equivariant homotopy theory. His contributions include studies on the Bousfield classes of H∞-ring spectra and the interplay between motivic and topological methods. His publications often intersect with algebraic geometry and representation theory, emphasizing the role of symmetry and duality in modern homotopy theory.
