Project Overview

Genetic correlates of Seasonal Affective Disorder (SAD) in a refugee population in upstate NY

Faculty Sponsor

Krista Ingram (




Circadian rhythms regulate numerous physiological processes such as sleep-wake cycles, body temperature, and metabolism and are influenced by light via interactions with circadian clock genes in the brain.  Limited sunlight exposure in the winter is thought to make evening chronotypes ('night owls') more susceptible to Seasonal Affective Disorder (SAD), compared to morning chronotypes.  We will study the prevalence and genetic correlates of SAD in individuals who have emigrated from equatorial populations into temperate environments, and investigate how circadian clocks influence mood across seasons.
