About Me

I started at MCLA in 2011. I love teaching in our close-knit department and enjoy the wide variety of courses that I teach. I am the advisor to the Math Society (our student math club), and I am in a Math Alignment group, connecting mathematics teachers and coordinators at the college and K-12 level in the Berkshires. I am also the Service Learning co-coordinator for MCLA and the treasurer for the college union. My outside activities include travel, hiking, cooking vegetarian food, and making pottery.

Research/Creative Interests

My research is in graph theory, especially chemical graph theory and planar graphs. Currently, I study fullerenes and benzenoids, which are graphical representations of carbon molecules. I often involve students in this research through independent studies or special topics courses.
