General Research Interests:

Design, construction, and evaluation of new spectroscopic instruments for the identification and quantification of trace amounts of inorganic species in complex real mixtures such as biological fluids and tissues, foods, fresh water supplies, and environmental samples

Design and construction of novel analytical instrumentation for atomic absorption, emission, and fluorescence measurements with emphasis on either simultaneous multi-element analyses or the development of dedicated single-element portable instruments

Use of chromatographic methods for sample introduction in atomic spectrometry and for the evaluation of trace metal sample preparation procedures
