U. Penn Fellows Embark on Two-Year Teaching Residency at Lawrenceville

Four new University of Pennsylvania Independent School Teaching Residency Fellows will join the Lawrenceville School faculty this fall. These aspiring and early teachers are earning their master’s degrees in education while completing an intensive, two-year teaching fellowship at Lawrenceville.

The Fellows work under the direction of an experienced Lawrenceville faculty mentor as teachers as well as coaches or assisting with community service initiatives. Each Fellow receives a House assignment, where he or she learns about (and becomes an important part of) Lawrenceville's dynamic residential life curriculum. In addition to their Lawrenceville duties, the Fellows are learning - and bringing back to campus – the most current research on best educational practices through their studies at Penn.

As an undergraduate at Wesleyan University, Joseph Ansel-Mullen tutored local middle school students in mathematics, language arts, science, and social studies. In the spring of 2024, Ansel-Mullen studied at Sorbonne Nouvelle Université in Paris, France, as part of a French language immersion program. During his summer college breaks, he worked at Waynflete Summer Camp—first as a counselor, then as a coordinator—where he mentored both campers and fellow counselors. In high school, he was a teaching assistant with Friends of Founders, a program that places college students in elementary classrooms to support teachers.

Claire Sizemore served as a STEM+ Learning Fellow at Princeton University, where she tutored undergraduates in introductory-level physics, chemistry, and biology. She has also engaged in extensive volunteer work, including teaching Sunday School in Phoenix, Arizona; providing child care for YoungLives in North Brunswick, New Jersey; and supporting physicians and patients at Penn Medicine Princeton Medical Center in Plainsboro, New Jersey.

Daniel Martin recently earned his bachelor's degree from Amherst College. At Amherst, he served as a grader in the Department of Mathematics and Statistics and was a Gregory S. Call Summer Student Research Fellow in the Department of Philosophy.
