Dr. Joseph Zoller

Biography

Joseph Zoller is a Lecturer in the Department of Biostatistics at the Fielding School of Public Health, University of California, Los Angeles (UCLA). He earned his doctoral degree in Biostatistics from UCLA and has conducted research under the guidance of Dr. Steve Horvath and Dr. Christina Ramirez. His research is centered on the development of statistical tools for measuring biological aging in humans and animal models, with a specific focus on DNA methylation-based biomarkers of aging, commonly known as epigenetic clocks. Zoller has contributed significantly to the field of epigenetic aging, particularly in the creation of numerous species-specific clocks for both mammals and non-mammals. His work includes the development of a cetacean epigenetic clock aimed at providing insights into aging and lifespan regulation in whales and dolphins, and a primate clock that refines the understanding of epigenetic aging in primate species. He has also played a key role in developing a universal pan-mammalian clock, a groundbreaking model that predicts biological age across a vast array of mammalian species. His recent, yet-to-be-published work as part of the Multicenter AIDS Cohort Study examines the effects of HIV and highly active antiretroviral therapy on aging biomarkers and immune cell compositions, offering critical insights into the intersection of infectious disease, immunosenescence, and biological aging. In his role as a lecturer, Zoller is passionate about teaching at both graduate and undergraduate levels, prioritizing equity in instruction and creating an inclusive learning environment. He employs active learning techniques and collaborative teaching methods to ensure students develop the practical knowledge necessary for success in future public health careers. Zoller’s commitment extends to mentoring the next generation of public health professionals and bridging the gap between biostatistical research and real-world applications in public health and medicine.
