Research Interests

I am interested in the environmental chemistry of heavy metals and metalloids, such as antimony, arsenic, bismuth, mercury, and silicon. Recently, new analytical methods have been developed which allow the study of several different chemical species of these elements at trace levels, and I employ these methods to elucidate their chemistry.

My research interests include the chemistry involved in the metabolism of metals by microorganisms; I am also interested in improving the current method of analysis, and the study of the chemistry of metals in other living systems.

Primary Areas of Work

-development of new techniques employing inductively-coupled plasma mass spectrometry ICP-MS and atomic fluorescence (AFS) detectors, and refinement of the hydride generation- inductively-coupled plasma mass spectrometry (HG/ICP-MS) method we currently employ for the trace-level analysis of organometallic species in environmental samples.

-the application of trace-level methods to the study of heavy metal species in living systems, including the study of the factors influencing the methylation of metals in biological systems, and the identification of methylation mechanisms.

-determination of the identity and significance of unknown organometallic species found in environmental systems.
