    Research Interests, Expertise:

    Academic and industrial experience studying metabolism of xenobiotics by diverse isoforms of cytochromes P450.  Recent work has focused on understanding how the aggregation and physical interactions of these enzymes and heme oxygenase-1 influence electron transfer from their common redox partner, the cytochrome P450 reductase.
