Research Interests
My research is mainly on Environmental Analytical Chemistry dealing with metal and organometallic compounds in water and biota. Chemical speciation of trace elements in different matrices is particular interest to understand their role in the ecosystem.

Current research projects include:

Ø   Trace metal speciation and bioavailability in aquatic systems

Ø   Metallomics of mercury and methylmercury

Ø   Ultra-trace analytical techniques for chemical speciation (HPLC-ICP/ESI-MS)
