Heather Guarnera

Heather Guarnera

Assistant Professor and Chair of the Computer Science Department

Computer Science

Biography

My research interests are in graph theory and algorithms, with a focus in the broad category of hyperbolic graphs and several interesting graph classes including Helly graphs, distance-hereditary graphs, AT-free graphs, and chordal graphs. I am largely interested in facility location problems and large-scale network analysis. My additional research interests include software engineering and algorithmic applications, such as mining software repositories and network visualization.

I particularly enjoy finding clean and aesthetic solutions to difficult problems in a manner that is easy to present and explain. One of my passions (in teaching, in research, and for sport) is exploring new and creative ways to solve problems.
