LADDER Lab: Our Team

Department of Psychological and Brain Sciences


Nancy Raitano Lee, Director of the LADDER Lab at Drexel University

Nancy Raitano Lee, PhD

Nancy Raitano Lee, PhD, leads the LADDER lab. She received her BS in Human Development and Family Studies at Cornell University in Ithaca, NY and her PhD in Child Clinical Psychology at the University of Denver. She is a licensed psychologist whose research seeks to characterize the neuropsychological and neuroanatomical phenotypes associated with different neurodevelopmental disorders in an effort to identify more effective targets of treatment to improve cognitive outcomes and ultimately quality of life for individuals and their families. Having grown up on Long Island, NY just 15 minutes from the beach and lived in Colorado near the Rockies for many years, she loves the ocean and the mountains and wishes that Philadelphia were about 60 miles further east or 1700 miles further west. Reluctantly accepting that this is not a possibility, she relishes in time spent outside in Fairmount Park and along the Schuylkill River. She also enjoys gardening, cooking, cabin camping and travel.
