Research Summary
Our current research focus involves the study of physical activity and antidepressant treatment interactions in the brain. Our studies seek to reveal the mechanisms of growth factor regulation and behavioral/functional recovery resulting from these interactions.

Electron microscopy, 6000x magnification, of a heart sample taken from an animal undergoing 45 min of ischemia followed by one hr of reperfusion. Damaged mitochondria are swollen, and have disorganized cristae and broken mitochondrial membranes.

Research Summary
Our research interests are in the area of cardiovascular metabolism. In particular we focus on the protection of mitochondrial structure and function in the setting of heart disease. Current projects involve the use of in vivo and in vitro models to study how various pharmacological agents protect mitochondrial structure and function in the setting of ischemia-reperfusion injury, and Friedreich's Ataxia.
