Sarah E. Millar is is the Albert Kligman II Professor and Vice-Chair for Research in the Department of Dermatology at the University of Pennsylvania. She is internationally recognized as a leading researcher in epithelial biology. Her research group has made seminal discoveries on the roles of Wnt inter-cellular signaling in epithelial development and regeneration. Dr. Millar’s research group also identified key roles for miRNAs in epidermal development and regeneration, and essential requirements for histone deacetylases in epidermal stem cell proliferation and survival. Her current research directions include elucidating the functions of Wnt ligands and their receptors, and chromatin repressive complexes, in skin and hair follicle development, stem cells and regeneration, and in inflammatory skin diseases. She is also developing genetic mouse models for human ectodermal dysplasias to delineate disease mechanisms and test potential therapeutic approaches. NIH has continuously supported Dr. Millar’s research since 2001. She serves as an editorial board member for Developmental Cell and Experimental Dermatology, was a Standing Member of the NIH ACTS study section from 2006-10, and has served on numerous other national and international grant review committees. Dr. Millar has received several awards in recognition of her research contributions including an NIH MERIT Award for her research on Wnt signals in skin and hair development and hair growth.
