Research Projects

  1. Metabolism, specifically lipolytic pathways, within the adipose was the focus of my early scientific life.  Postdoctoral work at OSU cultivated my interest in the role of visceral adipose inflammation in the etiology and progression of metabolic disease in human disease. An early project hypothesized that anti-inflammatory T-regulatory (Treg) cell populations play an important role, and I set about studying them in the context of the visceral adipose. My findings showed that Treg cells were abundant in normal chow-fed, lean mice as well as in humans with a normal body mass. In high-fat diet feeding in mice, the total and relative number of Treg cells dramatically decreased within the visceral adipose in mice. Similarly, markers for Treg cells in obese humans were lower than in a lean cohort. These findings led to further experimentation concerning the role of co-stimulatory molecules on antigen presenting cells in the adipose. While studying Tregs in human and mouse adipose, I discovered that miR-223 was dramatically upregulated in visceral adipose macrophages from obese insulin resistant patients vs. a lean cohort. I confirmed this in murine, diet-induced and genetic models of obesity and insulin resistance in mice. These findings led to the funding of a K01 by the NIDDK and publications on the topic of microRNAs (a non-protein-coding RNA species) in human and murine obesity and metabolic disease.
  2. Faculty-related research aims have expanded to study human cardiometabolic disease by examining tissues and fluids from healthy and disease patients using the most up-to-date high throughput techniques (e.g. RNASeq) and bioinformatic approaches to identify pathway abnormalities. Furthermore, the use of isotope-labeled substrates to determine microRNA-mediated changes in innate immune cell metabolism, often called metabolomics, is a method of primary interest. Innate immune cells include monocytes, macrophages, and dendritic cells (myeloid cells), are resident in nearly all human tissues, and are pivotal to potentiating and resolving tissue inflammation.
