Martin Scanlan - Associate Professor, Educational Leadership & Higher Education

Martin Scanlan is an associate professor in the Department of Educational Leadership and Higher Education in the Lynch School of Education at Boston College. Before joining the academy, Scanlan spent over ten years as a teacher and administrator.  He primarily worked in urban settings in schools serving traditionally marginalized students in Washington, D.C., Berkeley, CA, and Madison, WI. This laid a foundation for his teaching and scholarship interests, which focus on how schools can be organized to more effectively welcome all. Scanlan’s research primarily focuses on the organizational routines and practices of adults in schools, including the policies and procedures that shape these. While attending to multiple dimensions of diversity, his work has looked most carefully at how schools across sectors - including Catholic schools and public schools – can better serve students who have diverse cultural and linguistic heritages, as well as students with special needs. Scanlan has an extensive record of scholarship in academic journals reporting this work.
