Meet the Team

Eileen Crehan

Dr. Eileen Crehan is an assistant professor at Tufts University and head of the lab. A clinical psychologist by training, Eileen loves working with people of all ages and understanding what gets them out of bed in the morning! Her lab focuses on social development and promoting evidence-based practices informed by science and the communities utilizing these practices. In addition to the clinical applications of this knowledge, Eileen is interested in the methods and mathematics necessary for the pursuit of better programming and outcomes. Eileen is a proud Wellesley College alum where she majored in math and psychology as an undergraduate and a huge fan of the gorgeous state of Vermont, where she got her PhD.  Outside of the lab, Eileen spends her time perfecting the ideal breakfast spread (her specialty is blueberry pancakes), decorating cupcakes in outlandish ways, and doing puzzles. She enjoys playing soccer, trying to stay standing on a snowboard, and attempting to weightlift. Eileen was raised a Trekkie but married a Star Wars fan and thus is open to fans of either universe. A native New Englander, she is obviously a Red Sox  fan.
