Personal Statement
I have worked in adipocyte biology for over 25 years. During the first 14 years was focused on transcriptional regulation of adipogenesis and adipocyte survival. In 2004 I initiated studies to determine whether non-tissue resident progenitor cells traffic to adipose tissue and generate new adipocytes. My laboratory was the first to demonstrate that some adipocytes are produced from progenitors cells that have a hematopoietic rather than mesenchymal origin. We subsequently demonstrated that these unique adipocytes are 1) also produced in humans, 2) higher in female rather than male mice, 3) characterized by a proinflammatory, but low metabolic gene expression profile, and 4) produced from adipose tissue macrophage. Preliminary studies described in this proposal indicate that the highest number of these potentially detrimental adipocytes is found in pericardial adipose tissue. In 2009 I joined the faculty of the Gates Center for Center Regenerative Medicine and Stem Biology.
I was a Research Biologist and Director of Basic Research for the Pulmonary and Critical Care Section of the Veterans Administration Eastern Colorado Health Care System (VA ECHCS) from 2001 to 2008, and currently serve as a Research Biologist in the Geriatric Research, Education and Clinical Center (GRECC) at the same VA facility since 2016. I am also a professor at the University of Colorado Anschutz Medical Campus where I serve as co-director of the Obesity Cell Biology Program of the Colorado Obesity Research Institute. In this capacity I have priority access to the institute’s Energy Balance Core, Metabolic Core and Cell Biology Core. I also serve as Associate Director of our Specialized Center of Research (SCOR) on aging, gonadal hormones and obesity. Given my expertise in adipocyte and stem cell biology, our initial description and continued characterization of bone marrow-derived adipocytes, and access to state-of-the-art core facilities at VA ECHCS and University of Colorado, my laboratory is uniquely suited to complete the proposed studies.
