The Jun group is exploring the environmental impacts of human activities through improved understanding of the fate and transport of contaminants and nanoparticles. In particular, we aim to improve our understanding of the climate change impacts on water supply. We also are studying biogeological cycling in complex environmental systems from nanoscale to macroscale, with a view to conserving and restoring sound water environments.
In addition, our group is performing a comprehensive analysis of the potential risks associated with CO2 sequestration strategies to mitigate climate change and developing new treatment techniques and new catalysts for purifying drinking water and remediating contaminated water and soil.
