## Basic information

Office: Ayres Hall 208

Office hours: Mondays, Wednesdays and Fridays 10:10am-11:00am or by appointment

## Research interests

I am currently working in the area of coarse geometry, the study of large scale properties of spaces. I am interested in coarse invariants such as asymptotic dimension, Property A, coarse embeddability, and in objects which capture large scale behaviour such as the Higson corona and (maximal) Roe algebra. I am also interested in category theory and its applications to coarse geometry.

## Teaching information

Currently teaching Math 251: Linear Algebra from 11:15am-12:05pm and from 12:20pm-1:10pm in College of Nursing Room 107.

Previous courses taught as a GTA include Math 119: College Algebra and Math 125: Basic Calculus.
