Current Research

The Haas lab examines blood vessel growth (angiogenesis) in skeletal muscle and in adipose tissue.  We utilize biochemical, cellular and molecular biological approaches to study the stimuli and signalling pathways that cause endothelial cells to initiate angiogenesis as a result of exercise or changes in metabolic status (ie. energy overload).  A second key area of investigation is to identify and define the regulation of inhibitory signals that block appropriate angiogenesis in the skeletal muscle of individuals with diabetes and/or peripheral artery disease.
