Biographical Statement:

Brittany Jarrett is a doctoral student in the Division of Nutritional Sciences at Cornell University. She graduated from Cornell University with a BS degree in Nutritional Sciences in 2012 and is currently enrolled in the Division's Combined PhD/RD Program. She completed her dietetic internship and received her Registered Dietitian credential in 2014, after supervised practice at Cornell Cooperative Extension of Tompkins County and University of Rochester Medical Center Strong Memorial Hospital. 

Brittany's major field of study is Human Nutrition and her minor concentrations are Epidemiology and Reproductive Physiology. She is a member of Dr. Marla Lujan’s laboratory. Her dissertation research is focused on determining the impact of hypocaloric dietary intervention on ovarian morphology and function in overweight and obese women with polycystic ovary syndrome (PCOS). A primary objective of her work is to identify sonographic markers of reproductive function that can inform the prescription of therapeutic lifestyle interventions for women affected by PCOS.
