I am passionate about using science to protect and manage our soils and waters, which are our most valuable natural assets but are facing significant threats. The biogeochemistry research group I lead strives to understand and help solve complex environmental issues across multi-disciplinary boundaries (soil, water, ecology, human impacts). Our research has increased understanding of processes affecting the generation and fate of chemical species and contaminants (e.g. pH, metals, and nutrients), and how to manage systems to prevent undesirable impacts. Much of our current research is directed to assessing and predicting the effects of increasing droughts, reduced river flows, and sea level rise. The Murray-Darling Basin is a major focus of my research in this area.
