John Harnad (born Hernád János) is a Hungarian-born Canadian mathematical physicist.
His research is on integrable systems, gauge theory and random matrices.
[2] His work has had a strong impact in several domains of mathematical physics, and his publications are very widely cited.
[3][4] He has made fundamental contributions on: geometrical and topological methods in gauge theory, classical and quantum integrable systems, the spectral theory of random matrices, isomonodromic deformations, the bispectral problem, integrable random processes, transformation groups and symmetries.
In 2006, he was recipient of the CAP-CRM Prize in Theoretical and Mathematical Physics [5] [6] "For his deep and lasting contributions to the theory of integrable systems with connections to gauge theory, inverse scattering and random matrices".
