Research Interests: My recent research has focused on the regulation of mitochondrial proliferation and metabolism in the heart, with an emphasis on the role of the transcriptional coactivator peroxisome proliferator-activated receptor g coactivator-1a (PGC-1a) and its interaction with nuclear respiratory factor 1 (NRF-1). Using an inducible, cardiac-specific PGC-1a transgene, we showed that overexpression of PGC-1a induces mitochondrial biogenesis in neonatal mice, but causes cardiomyopathy in adult mice (Circ. Res. 94:525-533, 2004). More recent work has employed overexpression of PGC-1a and NRF-1 in primary cardiac myocytes cultures to delineate NRF-1-dependent pathways downstream of PGC-1a.
