My research focuses on the molecular mechanisms regulating cell metabolism and energetics. A long-term goal of my laboratory is to understand the role of mitochondria and metabolism in the pathogenesis of human diseases, in particular cardiovascular diseases.We have utilized molecular and genetic approaches to identify and perturb specific regulators in the key pathways of cardiac energy metabolism in mice and subsequently interrogated the physiological and biochemical responses in vivo during the development of heart failure using multi-nuclear NMR spectroscopy. Our past work focused on the oxidative metabolism and mitochondrial ATP synthesis in heart failure using mouse models of altered glucose and fatty acid metabolism in the heart. Our recent work seeks to decipher the mechanistic links between impaired oxidative phosphorylation and mitochondria-triggered cell death during chronic stresses. Results of these studies identified an important role of cellular redox state in diseases caused by mitochondrial dysfunction including cardiovascular and neurological pathologies.
The three key areas are:
- Energy metabolism in cardiovascular diseases
- Mitochondrial dysfunction and metabolic signaling
- Metabolic mechanisms of immunity, obesity and resilience to stress
