Dr. Halberg completed his graduate studies at the University of Copenhagen in 2009. Working in the laboratory of Dr. Philipp Scherer at the UT Southwestern Medical Center he studied the functional role of hypoxia and fibrosis in obese white adipose tissue. He did postdoctoral work in the laboratory of Dr. Sohail Tavazoie at the Rockefeller University studying the mechanisms of metastatic secretory programs in breast cancer. In 2015, he moved the University of Bergen to start his academic laboratory in the Department of Biomedicine. His laboratory seeks to better our understanding of the mechanistic connection between obesity and cancer.
