Research Goals

The overall goal of the lab is to elucidate the causes and consequences of cardiac health and disease through the mechanistic interrogation of novel molecular and metabolic pathways. Our team utilizes a wide-range of techniques from discovery-based screen, in vitro mechanistic approaches, in vivo models of exercise and heart failure, and the generation of novel mutant animal models with a goal of discovering new therapies for the treatment and prevention of heart disease.

Research Interests

As multiple comorbidities and cell types contribute to the development and progression of cardiovascular disease and eventual heart failure, the lab has developed a diverse yet targeted research portfolio to address these issues.

Current Interests:

  1. Understanding the mechanisms contributing to and distinguishing between heart failure with reduced (HFrEF) and preserved (HFpEF) ejection fraction.
  2. Identification of novel metabolic pathways which can be therapeutically manipulated to enhance cardiac energetics and mitigate maladaptive remodeling in HF.
  3. Defining novel pathways by which cardiac fibroblasts are activated and contribute to tissue fibrosis in.

Additional Interests:

  1. The effects of exercise on cardiac health and whether these pathways can be beneficially applied to HF.
  2. The interplay between metabolism and the epigenome in cell fate decisions and overall responses to stress.
  3. Metabolic regulation of striated muscle responses in health and disease.
