Young has served on numerous committees at the NIH related to promotion and tenure action, oversight of animal facilities, and coordination of summer student research. She has supervised dozens of research fellows and students. As of 2018, Young was a senior investigator and chief of the molecular biology of bones and teeth section. In August 2018, she was appointed deputy scientific director of the NIDCR division of intramural research.
