Background:

Analysis of food, dietary supplements, and cosmetics using X-Ray fluorescence spectrometry

We are using X-Ray fluorescence to determine the presence and concentration of elements in food, cosmetics, and dietary supplements. We have looked at kelp, ingestible clay, vitamins, salts, cocoa, and root spices (turmeric and garlic).  Future work includes analysis of mineral makeup.

Analysis of pesticides and pharmaceutical compounds in southeastern Michigan waterways

Atrazine is the most commonly used herbicide in the United States and is heavily applied to farm fields in the Midwestern region each year to control the growth of broad-leaf weeds. High concentrations of atrazine may ultimately enter nearby streams and rivers and remain high for several weeks. We are using liquid chromatography-mass spectrometry (LC-MS) and a quick, easy, cheap, effective, rugged, and safe (QuEChERS) extraction method to examine bioaccumulation of atrazine and its main metabolites (i.e., diaminochlorotriazine, deisopropylatrazine, and deethylatrazine in the digestive gland (liver) and muscle tissue of crayfish following exposures to environmentally relevant concentrations of atrazine.

Research Interests:

1. Analysis of food, dietary supplements, and cosmetics using X-Ray fluorescence spectrometry
2. Analysis of pesticides and pharmaceutical compounds in southeastern Michigan waterways
3. Cytochrome P450 and metabolism of xenobiotics
4. Use of active-learning strategies in the university classroom
