Ph.D., Washington University in St. Louis

Research Interests

Russell's 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, she 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.
