## Info

Starting in Fall 2021, I will be the calculus coordinator and lecturer at Colby College. Previously, I was a Visiting Assistant Professor at Bowdoin College for the 2020-2021 academic year, and a Norbert Wiener Assistant Professor at Tufts University for the 2019-2020 academic year. I graduated from Tufts University in 2019 under the direction of Kim Ruane. My main research interest is in geometric group theory. I received my Bachelor’s degree from Bowdoin College in 2013 and my Master’s from Tufts in 2015.

Here is my CV

## Research

My research is in geometric group theory. I am primarily interested in boundaries of CAT(0) groups, relatively hyperbolic groups, right-angled Artin groups, and right-angled Coxeter groups.

Here is a copy of my research statement. My papers can be found below:

*Right-angle Artin group boundarie**s*, joint with Robert Kropholler, on arXiv. Accepted, Proceedings of the AMS.*Boundaries of groups with isolated flats are path connected**Folding-like techniques for CAT(0) cube complexes**,*joint with Robert Kropholler and Rylee Lyman. arXiv. Submitted

For four semesters (Spring 2014-Fall 2016) I was an online course instructor for the Poincare Institute, an NSF-funded grant whose mission is to improve the teaching and learning of middle school mathematics by helping teachers deepen their understanding of key mathematical concepts and of how students learn. As a course instructor, I managed an online forum, facilitated discussions, and graded the teachers’ work.
