Title: Geometry and dynamics of groups acting on Gromov hyperbolic metric spaces
Abstract: In this talk, I will discuss two theorems about groups acting by isometries on Gromov hyperbolic metric spaces. The first theorem is a generalization of a theorem of Bishop and Jones ('97) and Paulin ('97) to this setting. The second is a construction of Patterson-Sullivan measures in a setting where compactness is not assumed. Both theorems are part of an ongoing collaboration with Tushar Das (University of Wisconsin - La Crosse) and Mariusz Urba\'nski (University of North Texas).

Title: Statistical knowledge for teaching: The case of informal line of best fit
Abstract: Study of the informal line of best fit marks students’ introduction to statistical association, a fundamental statistical concept. I will present three research studies concerning the knowledge for teaching informal line of best fit and engage participants in tasks that were utilized in the studies. Discussion regarding statistical knowledge for teaching, including important ways it differs from mathematical knowledge for teaching, will conclude the session.
