Research Summary

Dr. Jastreboff’s research seeks to elucidate neural mechanisms involved in obesity including neural control of eating behaviors. During her doctoral thesis work, Dr. Jastreboff became interested in understanding how metabolic perturbations, such as insulin resistance, hyperinsulinemia, leptin resistance, etc, affect neural mechanisms, which subsequently impact eating behavior and weight gain. To this end, she utilizes functional MRI to examine neural responses in obese adults and adolescents (insulin resistant and insulin sensitive) to various food cues (viewing images of high-calorie and low-calorie foods, ingestion of glucose or fructose drinks, etc). Dr. Jastreboff’s overarching goal is to conduct research that is clinically applicable for the treatment of obesity and has a clear public health impact to mitigate the obesity pandemic.
