Joseph Grzymski

Joseph  Grzymski is Chief Genomics Officer at Renown Health, founder of the Renown Institute for Health Innovation and an adjunct professor at the 91ԭƬ School of Public Health. He earned a dual B.A. in philosophy and biology from Bowdoin College, completed a Fulbright Fellowship in Norway, received his Ph.D. from Rutgers University and pursued postdoctoral work at Rockefeller University and the Desert Research Institute, where he later became senior director of the Applied Innovation Center.

Grzymski’s early research in environmental genomics led to landmark publications and nearly 100 peer-reviewed papers cited more than 4,000 times. He launched the Healthy Nevada Project (HNP) in 2016, which has now enrolled over 60,000 Nevadans, seeking to reach 100,000 participants. This population screening work has integrated clinical-grade exome sequencing into routine care through electronic health record (EHR) flags for cascade testing which includes risk-reducing interventions to support decision-making through dedicated genetic risk triage. The program focuses on improving uptake and actionability in clinical settings.

Under his leadership, the project has returned BRCA1/2 results to hundreds, built a "learning-health" data platform combining genetics, EHRs, environmental and social determinants, and filled critical gaps in cancer risk detection using natural-language processing. During COVID‑19, HNP pivoted to study vaccine hesitancy, infection patterns and environmental exposures, such as wildfire smoke. Supported by diverse funding sources, including Gilead-led research on liver disease, and as a founding partner in the Helix Research Network, Grzymski leads a multidisciplinary team translating genomic insights into preventive, community‑centered precision health.
