Dr. Ya Chieh Hsu

Biography

Ya-Chieh Hsu is a Professor of Stem Cell and Regenerative Biology at Harvard University and a Principal Faculty Member at the Harvard Stem Cell Institute. Her research focuses on the systemic changes in the body that alter cell-cell interactions governing development, regeneration, and injury repair. The skin, being the largest organ, provides a unique model for studying stem cell interactions and the microenvironments in which they operate. Hsu utilizes a diverse array of molecular, cellular, genetic, and genomic techniques to investigate the behaviors of stem cells regulated at both systemic and niche levels. Her aim is to understand how these regulations occur to meet physiological demands, and how dysregulation can lead to diseases. She completed her Ph.D. at Baylor College of Medicine, focusing on pathways controlling growth and proliferation using Drosophila as a model. Her postdoctoral research at Rockefeller University involved delineating the lineage hierarchy of hair follicle cells and investigating the signals that regulate hair follicle stem cells within the laboratory of Elaine Fuchs.
