Dr. Steve Horvath

Dr. Steve Horvath is a geroscientist whose research bridges the fields of biomarkers, precision medicine, genomics, and comparative biology. Full Professor at the David Geffen School of Medicine at the University of California, Los Angeles (UCLA) and founding Principal Investigator at Altos Labs. Widely recognized for his groundbreaking work on epigenetic aging clocks, Dr. Horvath developed the first multi-tissue epigenetic clock in 2013, which allows for the estimation of biological age across diverse human tissues. His research trajectory began with the publication of the first saliva-based epigenetic clock in 2011, continued with second-generation clocks for predicting mortality risk, and culminated in 2023 with his team’s development of the universal pan-mammalian clock: a single mathematical formula capable of measuring aging across all mammalian species. Beyond his academic research, Dr. Horvath founded the non-profit Epigenetic Clock Development Foundation. He has been named on Clarivate’s annual list of the world’s most influential scientific researchers every year since 2018.
