Biography

Catherine Pfaff is an Assistant Professor in the Department of Mathematics and Statistics at Queen's University. She holds a Ph.D. from Rutgers University - New Brunswick and an Honors BA from the University of Chicago. Her research interests lie primarily in geometric group theory, with a particular focus on rich intersection group theory, geometry, topology, number theory, ergodic theory, and dynamical systems. Pfaff's work is deeply engaged with the understanding of the outer automorphism group of free group actions and the deformation spaces of metric graphs. She is also involved in exploring the action of the mapping class group on surfaces in the context of Teichmüller space, which pertains to the deformation metrics of surfaces. Dr. Pfaff is known for her collaborative approach and enjoys engaging with mathematicians across diverse fields to explore applications of deformation spaces in mathematics.
