W. Stephen Wilson is a professor in the Department of Mathematics at Johns Hopkins. He served as chair of the department from 1993-1996.

His field of interest and research is homotopy theory, generally from an algebraic viewpoint. He tends to specialize in the use and development of complex (co)bordism, Brown-Peterson (co)homology and Morava K-theory.

Professor Wilson also has an appointment in the School of Education as a result of his interest in K-12 mathematics education.
