Team

We're a team of scientists on a mission to make the epigenome actionable.

We work across all of biology, from plants and fungi to human health.

Chuck Frazier, PhD

CEO, Founder

Chuck is the CEO & Founder of Nurture, an epigenomics infrastructure company on a mission to accelerate biological adaptation. He has spent his career turning scientific breakthroughs into commercial products, first at Apeel Sciences as an early employee where he helped scale the company from the lab into a thriving global business, then at Temporal Ag as a Founder and CEO, where he led the company from first proof of concept through field trials. Now at Nurture, he leads product and commercial strategy. Chuck holds a Bachelor’s degree in Chemical Biology from UC Berkeley, and a PhD in Chemistry from UC Santa Barbara.

Savannah Dearden, MS

CTO, Founder

Savannah is the CTO & Founder of Nurture, on a mission to make the epigenome an actionable layer of biology. She previously co-founded Temporal Ag, building tools to harness plants’ epigenetic memory for climate resilience and helped build the molecular biology function at Apeel Sciences, developing technology for predicting shelf life and reducing food waste. At UC Santa Barbara, she studied photonic nanostructures that produce structural color in marine animals to inform the design of next generation displays and solar cells, sparking a continued fascination with building technologies inspired by the inherent intelligence of biological systems.

Ryan Ward, PhD

Founding Scientist

Ryan Ward is a Founding Scientist at Nurture and the primary architect of Tellus, our biology-native informatics platform. He has spent his career making sense of messy data in vastly different places. He built predictive models of food spoilage and contamination for the FDA, put his master’s in Economics to work evaluating endangered species policy as a Natural Resource Policy Analyst in New Mexico, and ran CRISPR screens on antibiotic resistant bacteria during his PhD in Genetics at UW–Madison. Tellus is the tool he never had at the bench, making lab work visible and interpretable.

Amber Flores, PhD

Founding Scientist

Amber is a founding scientist at Nurture, where she leads experimental validation and perturbation work that grounds the Tellus platform in biological reality. She has pioneered genetic and epigenetic editing technologies across bacteria, yeast, and plants, and previously developed epigenetic reprogramming approaches to enhance heat resilience in tomatoes as a Senior Scientist at Temporal Ag. She earned her BSc and PhD in Plant Biology from UC Davis, where she was an NSF Graduate Research Fellow using CRISPR/Cas9 to improve agronomic traits in lettuce. Alongside her PhD, she also completed a year of MBA coursework and served as a Venture Fellow, conducting technical due diligence and deal sourcing at an early-stage Bay Area VC firm.
