Deborah Allen is on leave from the University of Delaware to serve in the National Science Foundation's Division of Undergraduate Education, where she is a Program Director for the Robert Noyce Teacher Scholarship program, and for the Interdisciplinary Training for Undergraduates in Biological & Mathematical Sciences (UBM), Course, Curriculum & Laboratory Improvement (CCLI), Research Coordination Networks–Undergraduate Biology Education (RCN-UBE), and Scholarships in Science Technology, Engineering, and Mathematics (S-STEM) programs. Before joining DUE, Allen served as PI of a NSF-funded Teacher Professional Continuum project, and continues to collaborate with the project's team of science and science education faculty who study pre-service teachers' progress through a reform-based teacher preparation program, and who co-teach courses for students in that program. Allen serves on the editorial board of CBE-Life Sciences Education and has co-authored a regularly-featured column on teaching strategies for that journal. She is the author of Transformations: Approaches to College Science Teaching (W.H. Freeman's Scientific Teaching Series, 2009).
