About Ruoyu Sun

I work in the area of environmental geochemistry and geology. My research publications cover analytic methods, field observations, and mathematic modelling. My work demonstrates a significant contribution in scientific understanding of elemental origins and cycling in an anthropogenic environment. I am particularly interested in using mercury stable isotopes to understand Hg cycling at global, regional and local scales. I developed the experimental procedures to accurately measure mercury concentrations and mercury isotope compositions in various kinds of samples such as coral, coal and shale. I used long-term natural archives like corals and lake sediments to investigate the changes of environment and climate. I also developed policy-relevant models to simulate the historical emission inventories of toxic elements, and the interaction of different geochemical processes important for elemental cycling.
