Curriculum
Vitae (Microsoft Word Format)
My research project lies at the chemistry-biology interface.
I measure oxygen-18 isotope effects on reactions of superoxide
dismutases (SODs) and copper(II) model systems. Isotope effects
on these reactions allow inner-sphere or the outer-sphere
mechanisms of electron transfer during superoxide oxidation
to be differentiated. The implications of this research are
important for understanding function of SODs and design of
SOD mimics. |

My current research interests lie in understanding the mechanisms of hydrogen transfer reactions. One goal is to use modified Marcus theory to explain enzyme catlaysis in terms of measurable quantities like reorganization energy, driving force,
and hydrogen tunneling probability.

My research encompasses the study of
metal-mediated electron transfer mechanisms for the activation
of molecular oxygen. |

My research explores the mechanism
by which the heme-containg enzyme cyclooxygenase, using a
protein radical for catalytic oxygenation reactions. |
