I work in the fields of bacterial physiology, bioenergetics and enzymology.  I am most excited when tackling basic biological questions that have the potential to impact public health.  Interdisciplinary approaches are often key when answering these questions and I try to exploit my background in biochemistry, microbiology, biophysics, and organic chemistry to the fullest.  

 My PhD thesis was on the biochemical characterization of heme-copper oxygen reductases (HCOs) from various bacteria.  What makes these enzymes truly exciting to me is the fact that they make attractive drug targets.  As a terminal oxidase in the respiratory chain, the function of these enzymes is crucial to the survival of any living organisms, including pathogens, which rely on aerobic respiration.

 I try to extend my excitement to classrooms where I employ active learning methodologies to engage our students in performing actual scientific research, contributing in a real way to advancing scientific knowledge.  I believe exposing students to open ended research questions is the best way to stimulate higher order cognition.
