PhD student, Water recycling and evaporation




Staff profile

Patrick is a PhD student working with Line Gordon, exploring moisture recycling - particularly, how evaporation from the land-surface returns downwind as precipitation


In 2012, he and his co-authors published a paper describing a method for defining the upwind area that contributes evaporation for a downwind region's precipitation, known as a precipitationshed. Patrick's current PhD work probes deeper into the questions begun in the 2012 paper, specifically exploring how social-ecological systems become more vulnerable or more resilient with changes to moisture recycling regimes.

Prior to joining the centre, Patrick founded an environmental consulting firm, with projects exploring water security in drylands, ecosystem service trade-offs, and climate change vulnerability and adaptation. Additionally, he has worked with SEI and UNEP on a report exploring trade-offs between water use efficiency and ecosystem services, as well as co-authoring a book chapter on drought, conflict, and food policy, in a publication sponsored by the African Centre for the Constructive Resolution of Disputes (ACCORD).

Patrick holds a MSc from the department of Civil and Environmental Engineering at the University of Washington, and BA in Biology from Willamette University.
