Welcome to my relatively new web page (under construction)

I am a topologist, particularly interested in manifolds, homotopy theory, and various relations between manifolds and homotopy theory. I like to use categories and functors and natural maps.

When and where to find me

Office: Kassar 212 (151 Thayer St., Providence, RI 02912)

During the semester I am on campus on Tuesdays, Thursdays, almost all Wednesday afternoons, occasional Fridays and rare Mondays.

Teaching

In Fall of 2024 I taught Math 2410, an introductory graduate-level course in algebraic topology.

In Spring of 2025 I will be teaching Math 2720W, a graduate topics course on K-theory (mostly the algebraic kind). The course will meet Tuesday and Thursday 1:00-2:20 in Kassar 105.

DGS work

I am Director of Graduate Studies for the Mathematics Department. I have been DGS for about 17 years (not consecutive) during my 36 years at Brown.
