Was nominated by the Department of Mathematics and was appointed to 2015-2016 CTL Graduate fellow for teaching excellence of the University of Pennsylvania.

CTL’s Graduate Fellowship for Teaching Excellence program honors graduate students who are dedicated to excellent teaching and is designed to foster conversations about teaching to help graduate students develop as teachers. Graduate Fellows organize and facilitate teaching workshops in their departments and across the university, observe graduate students teaching and offer feedback, and meet regularly as a fellows group to discuss teaching practices. Candidates for this fellowship must be nominated by their department; the call for nominations goes out to graduate chairs in the spring semester.
