About the Presenter
Dominik Weiss is a professor of engineering at Imperial College London, where he leads the environmental geochemistry research group. His research is focused on understanding the chemical and biological processes that control the transformations, ecological effects, and cycling of trace metals in the environment.
About the Presentation
Nontraditional stable isotope systems are now widely explored as potential novel tools to study a wide range of earth and environmental system processes. In his presentation, Dominik Weiss will:
– Discuss the analytical challenges associated with accurate and precise isotope ratio measurements—and how to overcome them
– Present a conceptual model explaining isotope fractionation in the plant soil environment, and discuss its possible implication for identifying Zn efficiency mechanisms in rice
– Present new data on Zn and Cu isotopes in atmospheric particles and show how these new systems might help us to improve our understanding of trace element cycles in the urban environment
