Biography

Dr. Berglund came to UT Southwestern after receiving his PhD from Vanderbilt University where he studied how glucagon action on the liver affects hepatic nucleotide levels as well other aspects of hepatic and whole-body metabolism. This move offered an opportunity to combine Dr. Joel Elmquist’s resources studying central regulation of metabolism and array of genetically modified mice with his expertise studying in vivo physiology. His specific areas of interest are how the hormones leptin and glucagon act in the liver and brain to control substrate metabolism and potentially energy balance. He is also interested in how CNS signals are transmitted via hormonal or neural mechanisms to modulate specific organs. These questions are relevant to diabetes and obesity. His personal interests are his family and outdoor activities.
