  • I am a Professor in the Department of Pure Mathematics at the University of Waterloo, and a member of the Geometry & Topology research group. My area of research is differential geometry and geometric analysis. Specifically, I work on manifolds with U(m), SU(m), G2, or Spin(7) structures. This includes: the construction of torsion-free compact examples; the study of their moduli spaces and the extra geometric structures on such moduli spaces; conical singularities of such manifolds; calibrated submanifolds; Donaldson-Thomas connections in G2 and Spin(7) geometry; properties of special torsion classes; and geometric evolution equations in the context of special holonomy and calibrations.

    I am on the Editorial Board for the journal Pure and Applied Mathematics Quarterly published by International Press. I encourage you to submit your high quality manuscripts to PAMQ for consideration, and to select me as the handling editor if the content matches my research expertise.
