2 Michael Jerome Hopkins is a mathematician at Harvard University. He got his PhD from Northwestern University in 1984, advised by Mark Mahowald.
Hopkins is a world leading researcher in algebraic topology and (stable-)homotopy theory.
Among his notable achievements are his work on the Ravenel conjectures, the introduction and discussion of the generalized cohomology theory tmf and its string orientation, a formalization and construction of differential cohomology, the proof of the Kervaire invariant problem. More recently via Jacob Lurie‘s work on the cobordism hypothesis Hopkins participates in work related to the foundations of quantum field theory.
