Associate Professor of Instruction, Temple University

Lori A. Shorr

Dr. Lori Shorr’s interests in education stem from the two paths that brought her to Temple. First, she pursued her doctoral degree in critical and cultural studies with an emphasis on how social changes are connected to, and influenced by, narratives –be they political, historical, social or personal. Second, she has culminated a 20-year career in policy development and implementation from special assistant to three Pennsylvania Secretaries of Education to eight years as the chief education officer for the City of Philadelphia, which entailed setting the mayor’s policy agenda in K-12 and higher education. The courses she teaches and the work she continues to do in the community, as well as the mentoring she does with students, is therefore centered around the theories which help to explain how power, representation, constructions of social justice and community interact with the “lived experiences” and policy realities in specific historical junctions. She is currently working on building a collaboration of regional school leaders who are committed to working on communication across sectors of education (district, charter, private) to increase opportunities for success for all students through holistic and project-based instruction. She remains committed to increasing the capacity of the schools and the nonprofit sector in Philadelphia in order to bring about equity in educational opportunity in hopes of a more just city.

As principal of West Brooklyn, she worked in partnership with Good Shepherd Services to replicate its model transfer school, serving over-aged/under-credited students in Sunset Park, Brooklyn, the community where Liliana was born and raised. Through working in partnership with students whom the traditional high school systems had failed, families, and staff, Liliana saw the potential of a school that was built around the needs of those within it. Liliana credits the partnership with Good Shepherd Services and the incredible staff at West Brooklyn with making it one of the top performing transfer schools in the city.
When presented with the opportunity to pursue a doctorate, her focus was building programs at state and district levels that effectively support staff to meet young people’s needs. After completing her studies, Liliana became Vice President of the New York City Leadership Academy where she led programming for principals and their teams in school districts across the country to assist in their transformation efforts. Liliana holds a Doctorate in Education Leadership (EdLD) from the Harvard Graduate School of Education, a BA and MAT from Brown University, and a Specialist Diploma from Queens College.
