RESEARCH INTERESTS:

My research interests include the following areas: photosynthetic efficiency, higher plant pigments; soybean proteins as allergens.

MAJOR PROJECT ACTIVITIES:

My major research is to determine if plant metabolism can be made more efficient under conditions of water stress. We are using a combination of biochemistry, molecular biology and transgenic plants to determine if enzymes normally present in plant cells can reduce rates of a wasteful process called photorespiration. I am also interested in professional development of undergraduate science teachers and I have been actively involved in NSF-funded projects to develop new laboratory exercises for students and new distance education courses.
