Personal profile

Research Interests

My present research program is directed towards understanding the key environmental processes that control the fate of metals in aquatic systems. Other current emphases focus on understanding how the chemical speciation of metals control their bio-uptake (Hg in particular). I am also working on developing the theoretical and analytical framework for assessing the chemical speciation of metals in complex environmental samples. In addition, I collaborate with other PIs from Northwestern bringing my experience in synchrotron radiation to perform either spectroscopic - X-ray Absorption Spectroscopy -, scattering and x-ray computer microtomography experiments.
