Research Interests

I am an environmental chemist with research specialization in the fate and transport of organic chemicals in the environment; water chemistry; photochemically driven oxidation; photocatalysis; kinetics, trace organic analysis; combinatorial chemistry and free radical chemistry.

Introduction:  My research is broadly centered on studying the fate of organic chemicals in the environment.  This includes man-made chemicals like pollutants, pharmaceuticals and pesticides; and also naturally occurring chemicals like biotoxins, signaling molecules and various plant products.  My group applies advanced analytical techniques to learn how these chemicals are transformed in or removed from the environment.

Analytical approaches:  Environmental analyses need to be fast, sensitive and selective.  We use whatever analytical tools we need to, but most often work with gas or liquid chromatographs with mass spectrometric or spectroscopic detectors.  We also use absorbance or fluorescence spectroscopy (steady state and time resolved); various electrochemical techniques, nuclear magnetic resonance spectroscopy, infrared spectroscopy, and transmission electron microscopy.

Experimental approaches:  Environmental chemists spend time in the field making measurements and in the laboratory testing explanations for their field work.  My group has done field work measuring the fate and distribution of organic chemicals, nanoparticles, transition metals, and oxidants like hydrogen peroxide or the hydroxyl radical.  We quantify the relationships between those analytes in the laboratory with sophisticated environmental modeling techniques.  We use robotic systems to generate solutions modeling hundreds of different environmental conditions simultaneously, a process called combinatorial environmental chemistry.  These solutions are spiked with a variety of probe molecules and contaminants, and then subjected to weathering processes in the laboratory.  This allows us to rapidly interrogate environmental systems for their ability to promote photodegradation, free radical oxidation, complexation of transition metals, etc.  Coupling this approach with field monitoring is one of the surest ways to make sound predictions about what will happen to pollutants as they are processed by environmental systems.
