Current Research, Academic Interests and Areas of Expertise
Analytical chemistry with emphasis on spectrometry, chromatography and capillary electrophoresis with applications in biological or environmental samples. Recent areas of research have included:
- Separations and thermodynamic studies of chiral compounds using high performance liquid chromatography
- Monitoring acidic deposition and effects on plant waxes by gas chromatography with mass spectrometry and also ion chromatography
- Fluorescence detection and post-column derivatization for electrophoresis
- Uses of Raman spectroscopy in chemical analysis
I also conduct research in phytoremediation of metal-contaminated soils and develop new group project-based undergraduate curricula in chemistry education.
Professional Background Highlights
My professional commitment is to excellence in teaching, innovative curricula and undergraduate research. I am an analytical chemist and teach courses in general and analytical, plus laboratories in biochemistry and spectroscopy. I am active in development of new types of chemistry curricula and project-based laboratory experiments and courses. As assessed in student outcomes and surveyed attitudes, these open-ended courses appear to improve the interest, confidence and achievement of students. I have received a number of significant grants for curriculum development including multiple grants from the National Science Foundation. While my research interests have been varied over the years, the common thread has been the development of innovative methods of separation, both utilizing chromatography and capillary electrophoresis, with sensitive and selective detection primarily with molecular fluorescence. Most of the applications of my research work have been in environmental chemistry and pollution analysis, although I also have a fairly strong background and interests in bioanalytical chemistry. I came to the University of Redlands in 2003 after seventeen years at the University of North Carolina at Asheville. I have mentored over 50 undergraduate students in research during my professional career. In addition to my interests in chemistry, I have also taught many courses related to science and society in a variety of disciplines including Women's Studies and interdisciplinary humanities programs. I have served in numerous service and officer positions for the American Chemical Society.
