RESEARCH FOCUS

According to the National Health and Nutrition Examination Survey two-thirds of U.S. adults are either overweight or obese. The estimated direct costs associated with obesity, metabolic syndrome, and Type 2 Diabetes is approaching 100 billion dollars annually.

My research goals are to examine the changes in metabolism that occur in the presence of obesity and/or Type 2 Diabetes and to develop clinical biomarkers and potential therapeutic targets.  Currently, my lab focuses on a family of secreted proteins termed C1q TNF-Related Proteins (CTRPs). CTRPs are a novel family of secreted proteins, which circulate in the blood stream.  Many members of the CTRP family are adipokines, meaning secreted from adipose tissue, but the CTRP family includes proteins that are secreted from a variety of tissues. For example, CTRP15 (also called myonectin) is secreted primarily from skeletal muscle and therefore is called a myokine.

My research focuses on characterizing the functions of these proteins, using molecular, biochemical, in vitro and in vivo approaches.  Much of my initial work demonstrates that the CTRP family of proteins contribute metabolism and are dysregulated with obesity. However, the functions of the CTRP protein family are still actively being investigated.
