I am a biogeochemist with a broad interest in the cycling of elements through the Earth system. My current research focuses on the role of glacial meltwater in downstream biogeochemical cycles. I take particular interest in the potential of meltwater to influence the structure and productivity of ecosystems, subglacial biogeochemical weathering processes, and the mobilization of nutrients and toxic elements in freshwater environments and export to coastal ecosystems. In the past I have been involved with research ranging from biogeochemistry of supraglacial (surface ice) environments (cryoconite – “ice dust”), to ice sheet hydrology (the flow of water and sediment through glaciers) and water quality of groundwater aquifers in the Bahamas.
A large part of my research is based on field observations (sample collection for analysis in labs and electrochemical sensor deployment). Fieldwork has taken me to remote areas of the Arctic, Patagonia and the Himalayas. This has included sampling in Svalbard, Greenland, India and Chile. Additionally, I am a collaborator on a subglacial lake drilling projection in Antarctica (www.salsa-antartica.org), have also worked in the tropics sampling groundwaters and have taught field skills on multiple field trips to the European Alps.
