Professional Experience

                     

Research Experience

 

Post-doctoral Research, Department of Chemistry, University of Minnesota (Twin Cities).

· September 2003 – July 2006.  Professor Christopher J. Cramer and Professor William B. Tolman, advisors. 

¨        Studied the catalytic mechanisms of the dopamine ß-monooxygenase (DßM) and peptidylglycine α-hydroxylating monooxygenase (PHM) enzymes by quantum chemical modeling of the active sites.  The effects of different coordination environments for the copper atoms on dioxygen activation and substrate hydroxylation are determined.  This work represents the first application of theoretical methods to model specific reaction mechanisms in these enzymes and will greatly increase understanding of the reaction chemistry of monocopper complexes in general.

¨        Modeled dioxygen activation and substrate hydroxylation in biomimetic monocopper complexes being developed in the Tolman group.  This work was carried out in conjunction with parallel experimental studies in the Tolman group.

¨        Mentored and collaborated with an undergraduate student as a part of these two projects, leading to publication (see #1 in publications).

Graduate Research, Department of Chemistry, Columbia University.

· January 1999 – August 2003.  Professor Richard A. Friesner, advisor. 

¨        Based upon ab initio quantum chemical studies on a large-scale model, proposed for the first time complete and realistic catalytic cycles for dioxygen activation and methane hydroxylation by soluble methane monooxygenase, a metalloenzyme that is found in methanotrophic bacteria. Computational results were found to be fully consistent with and provide explanation for experimental data.  Further work on this system succeeded in explaining the different rates and kinetic isotopic effects seen in the reaction of methane monooxygenase with substituted methane substrates.

¨        Use of a novel mixed quantum mechanics/molecular mechanics method (QM/MM) to determine the origin of the different rates for the deacylation step in the hydrolysis of ß-lactam antibiotics performed by penicillin-binding proteins and class-C ß-lactamases.  This research played a role in understanding the differences in reactivity of the two enzymes towards ß-lactam antibiotics and contributed to an understanding of the mechanism of bacterial antibiotic resistance.

Undergraduate Research, Department of Chemistry, Carnegie Mellon University.

· May 1995 - August 1995, May 1996 - August 1996, May 1997 - August 1997, January 1998 - May 1998.  Professor David Yaron, advisor.
