My research focuses on the effects of shifting physicochemical conditions in ancient and modern marine ecosystems that may be related to significant changes in the atmosphere, continental weathering, and anthropogenic impacts. Specifically, I am interested in the effect of changes in terrestrial weathering and freshwater input on shallow water communities throughout the geological record and present day. I am also interested in the effects of changes in water chemistry, specifically nutrients, on the composition of benthic communities. 

I also examine the effects of diagenesis on carbonate sediments and rocks, to determine whether the original physiochemical conditions that were recorded in the rocks have been altered through post-depositional fluid-rock interactions, thereby altering the geochemical signals we use to interpret past environments and how the physical properties of the rocks may have also changed. Much of my research over the last decade has focused on dolomitization related to major tectonic events in Egypt and in western Canada.
