She currently holds a seat on BWH’s Board of Advisors as well as the Newborn Medicine and Reproductive Health Advisory Board. At Penn, Tamsen serves on the School of Arts and Sciences Advisory Board in addition to her role at Basser.

After graduating from the University of Pennsylvania, Tamsen earned her Master's degree in Genetics.
