A major area of research interest is on chemical speciation of trace elements. The main interest is on the (thio)arsenic speciation, in light of its significant impact on the environment and human health using (IC)HPLC-ICP-MS/ESI-MS/MS techniques.
Polysulfide redox chemistry
Developing analytical techniques for the speciation analysis of trace levels of (thio)arsenic compounds in environmental and biological samples.
Cellular uptake of arsenic, antimony, bismuth, and tin and their methylated derivatives.
