 His research interests include supersymmetry, string theory and applications of generalized complex geometry, and with S. J.Gates, M. T. Grisaru, and W. Siegel, Rocek coauthored "Superspace, or One thousand and one lessons in supersymmetry" (1984), the first comprehensive book on supersymmetry.He is the local coordinator of the annual Simons Workshop in Mathematics and Physics jointly hosted by Yang Institute for Theoretical Physics and the Department of Mathematics of the Stony Brook University.
