Nancy S. Wexler, PhD, has devoted her career to finding treatments and a cure for Huntington’s disease. Her pioneering field work in Venezuela with the largest known family with HD led to the discovery of a genetic marker in 1983. This achievement validated a new approach to mapping genes, including many other disease genes, and helped launch the Human Genome Project. It also made possible a predictive test for HD. Following the marker discovery, she helped organize and lead the Huntington’s Disease Foundation’s historic international collaborative research group that, in 1993, identified the expansion in the HD gene itself.
Nancy has also led efforts to ensure fair use of genetic information and improve care for those living with HD and other neurodegenerative conditions. She served as executive director of a landmark congressional commission on Huntington’s in the 1970s and, in the 1990s, chaired the first Ethical, Legal, and Social Issues Working Group (ELSI) of the Human Genome Project. All these achievements led to numerous awards and honors, including the Franklin Prize in Life Science (2007), the Cold Spring Harbor Double Helix Medal (2019), and the Lasker Prize for Public Service (1993). She currently lives with HD in New York City.

Sarah Hernandez, PhD
Dr. Sarah Hernandez oversees the Foundation’s scientific research portfolio by managing the grants program, acting as the scientific liaison, and coordinating scientific programming through webinars, workshops, and conferences. Sarah enthusiastically supports the mission of the HDF, working closely with its Scientific Advisory Board to identify the most promising research and accelerate treatments for Huntington’s disease.
Sarah learned at a young age that her family was affected by Huntington’s disease, motivating her to learn more and inspiring her to become a scientist. In 2015, she received a PhD in Biology and Biotechnology from Worcester Polytechnic Institute. For her postdoctoral studies, she joined the lab of renowned Huntington’s disease scientist Leslie Thompson, PhD, at the University of California, Irvine and Chair-Elect, HDF Scientific Advisory Board. There she worked on understanding the molecular consequences of Huntington’s disease to cells of the brain using stem cells and fruit flies. In 2021, she was honored as the recipient of the Huntington’s Disease Foundation Nancy S. Wexler Young Investigator Prize, presented to a researcher whose work represents the highest caliber of excellence, diligence, and creative thinking. Additionally, Sarah is an editor for HDBuzz, writing articles about Huntington’s disease-related science and research news in plain language for the patient community.
