Research activities

We work on the biogeochemistry of metals (iron, cobalt, zinc, copper, chromium, and other), sulfide, and specific organic compounds (folic acid, glutathione, and others), in the oceanic water column, coastal waters, estuaries, and lakes. We study speciation of metals with organic matter, their redox speciation, and the speciation of specific organic compounds. We do get quite desperate sometimes. So, we decided to do some work on microorganisms too: we are looking for feed-backs between speciation and bio-availability. We are now growing Emiliania huxleyi and other algae and even some bacteria in "realistic" cultures. This is of course different from the unrealistic cultures which most other people may be growing.

We mostly use cathodic stripping voltammetry, usually with ligand competition to determine metal speciation.
