My current research investigates the relationship between the aging circadian clock and alcohol neurobiology. Currently, the majority of basic alcohol research focuses on alcohol’s effects during adolescence and young adulthood. Even though the aging population is increasing in the U.S. and more than 85% of alcohol-induced liver cirrhosis deaths occur in individuals 45 years and older, very little research investigates the effects of alcohol during middle and old age. One of the factors potentially underlying age-related pathologies is the weakening of the circadian system with age. As such, the goal of my dissertation research is to identify the endogenous factors mediating the age-related decline in circadian regulation of alcohol sensitivity and mortality and to determine whether strengthening entrainment of the circadian clock in aged animals is sufficient to ameliorate the toxic effects of alcohol. Due to its great genetic power, ease of maintenance and conserved genetic, physiological and behavioral traits, I use Drosophila melanogaster (the fruit fly) as the model organism for my research studies.
