Timothy Bartness is a world-renowned obesity researcher and Director of the Center for Obesity Reversal at Georgia State University. Also a Regents’ Professor, Bartness has studied obesity
for more than 30 years.
Bartness is passionate about tackling and reversing the nation’s obesity epidemic by using a basic science approach. He has directed researchers in the center to study two ways to reduce obesity, decreasing food intake and increasing energy expenditure, with a primary focus on the mechanisms underlying the control of food intake and energy expenditure.
His lab is focused on how the brain communicates with adipose tissue (fat) through the sympathetic nervous system and how fat communicates with the brain through the sensory nervous system, a bidirectional communication that seems to be responsible for controlling the breakdown of fat and functioning as the principal way mammals decrease their body fat. He is also interested in the brain chemicals that control food acquisition and storage, behaviors that can lead to obesity. He has uncovered a number of neurochemical factors that promote food hoarding in
non-human animal models.
The Basic Science
We study obesity and related diseases, such as diabetes, hypertension, chronic inflammation and some cancers. Our researchers from diverse backgrounds will focus on two ways to reduce obesity, decreasing food intake and increasing energy expenditure.
