Our research is focused on understanding how microbes influence ocean biogeochemistry. We are particularly interested in how micronutritional requirements (demand for vitamins and trace metals) shape interactions between phytoplankton and bacteria and what the consequences of those requirements and interactions are for global carbon, nitrogen, and sulfur cycling.  We are also interested in the evolutionary context behind maintenance or loss of trace nutrient dependencies in marine microbes.  We use quantitative mass spectrometry- based proteomic techniques, paired with field and laboratory experiments, to ask these questions.

We are looking for qualified students (honours, Masters, PhD) to join our team.  Students should have an A- average to apply.  Example research projects can be found here.
