Prior to joining Altos, Steve was a Professor of Human Genetics and Biostatistics at the University of California, Los Angeles. His research lies at the intersection of several fields including biogerontology, anti-aging clinical trials, epigenetic biomarkers of aging, epidemiology, systems biology, and comparative biology. Steve and his UCLA colleagues published the first epigenetic clock for saliva in 2011, the first pan-tissue clock (2013), and the first pan mammalian clock (2021). He is also known for developing weighted correlation network analysis (WGCNA), a widely used data mining method used in genomic applications. The recipient of several awards, Steve has been on Clarivate’s annual list of the world’s most influential scientific researchers every year since 2018.
