In Spring 2024, I am teaching Multivariable Calculus. I regularly teach Differential Geometry, Abstract Algebra, Multivariable Calculus, and Calculus I, among other things. I have also completed the iBme mindfulness teacher training program. I enjoy sharing mindfulness with students and working with them on their practice.


My current research interests include the differential, spectral, and metric geometry of orbifolds. In this short interview, I talk a bit about geometry and the work that I do (31:47).

    Other Interests

    Along with teaching and research, I enjoy running, reading, spending time with my family, and meditation and ethics. When things are quieter, I also like to draw.
