I wear two hats. As an early modern historian of science and philosophy I have focussed my research on the intellectual history of science, focussing on figures such as Francis Bacon, William Gilbert, Isaac Barrow. I follow in particular the context-dependent articulations of what it means to know. As an STS researcher I work very much in the present, particularly in tracing the life of environmental sciences as they emerge from the lab/field, into the realm of government regulation, industry practice, and societal negotiation of resource extractive industries. The disaster that was DWH has focussed my attention on the role of oil spill response technologies (current and potential) and their capacity to impact how risk, planning and response is framed in Canada and internationally.
