Research Interests:

My research focuses on the development of Hg stable isotopes as tracer for sources and processes in the environment. My main research interests are the exchange of mercury between the atmosphere and terrestrial ecosystems as well as transformation and transport processes in soils. I have recently been working on boreal and Arctic ecosystems. Our current work focuses on the uptake of atmospheric elemental mercury by vegetation across Europe. To achieve our goals, we will combine the novel mercury isotope fingerprinting tool with remote sensing and modeling techniques. I am also interested in developing new analytical techniques and new applications using Hg stable isotopes.
