My research interest focus on aqueous geochemistry, chemical oceanography, and geomicrobiology. Our expertise is in the cycling of trace metals and inorganic chemical species at oxic-anoxic interfaces in freshwater and marine systems (water column and sediments). Our research involves extensive field and laboratory work as well as mathematical modeling.
Instrumentation:
Two DLK-60 an a DLK-100 potentiostats (Analytical Instruments Systems, Inc.) for voltammetric measurements
A DLK-SUB III potentiostat with micromanipulator (Analytical Instruments Systems, Inc.) for autonomous in situ voltammetric and pH measurements in sediments
A DLH-60 potentiostat (Analytical Instruments Systems, Inc.) for in situ voltammetric measurements in aquatic systems with telecommunication capabilities for remote sensing
A hanging-mercury drop electrode (HMDE) system (Metrohm VA663) with potentiostat (Ecochemie)
An ICP-MS (Agilent 7500a) in a class-100 and class-1000 clean rooms
