About Me

The most exciting phrase to hear in science, the one that heralds the most discoveries, is not ‘Eureka! I found it! But 'that's funny...’ ”

― Isaac Asimov

Research

Research in our lab is focused on investigating novel epoxy metabolites generated from the metabolism of polyunsaturated fatty acids. We primarily investigate the role of CYP epoxygenase metabolites of arachidonic acid (omega-6), called epoxyeicosatrieanoic acids (EETs), in maintaining tissue homeostasis and reducing injury. However, we have recently begun exploring the CYP-derived metabolites of docosahexaenoic acid (omega-3), called epoxydocosapentaenoic acids (EDPs).  The main areas of specialization include cardioprotection, ischemia-reperfusion, PUFA, mitochondria, toxicology, cytochrome P450 system and mechanisms of cellular death.

Major Research Questions:

1) What role do EETs and EDPs have in cardiac physiology and pathophysiology in both young and aged hearts?
2) What are the intracellular targets of EETs and EDPs?
3) How do EETs and EDPs limit mitochondrial damage from ischemic injury?
4) Can we design and develop novel compounds based on the chemical structure and function of EETs and EDPs?
