Research

How do social environments become biologically embedded to affect health and disease? My research combines social epidemiology and the biology of stress to explore the ways in which experiences during critical periods of development can shape health trajectories and interact with later exposures to shape health outcomes. My research focuses on the ways in which social determinants of health affect our biology, including inflammatory and metabolic processes, the endocrine responses to stress, and gestational outcomes, all of which influence and predict a wide range of diseases. I am interested in questions such as: Can environmental interventions reduce the harmful effects of early life adversity? How do prenatal and postnatal environments influence inflammatory and metabolic outcomes? I am particularly interested in the environmental and social circumstances which can produce vulnerability or resilience, as well as the biological mechanisms responsible for behavioral and health outcomes, in order to identify opportunities for intervention.

“We know the virus spreads when people move around, when people are sharing space and sharing air, so reducing that should reduce the spread,” said Kat Saxton. “But people are also tired of COVID.”

Kat Saxton wrote an opinion piece with Craig Stevens in the Mercury News about the CDC's new Covid-19 testing guidelines and how it should be ignored as it is scientifically unfounded.
