I study the impacts of urban and agricultural development on local climate. I develop and apply numerical models across multiple scales, from individual streets to whole cities and their rural surroundings. Model applications include assessment of urban heat islands and their causation, mitigation of urban heat with vegetation and reflective surfaces, assessment of pedestrian thermal comfort, and dynamical downscaling of global climate model projections. I have particular expertise on modelling the local climate impacts of urban street tree planting. For example, I try to understand how much cooler our cities will be in summertime if more trees are planted, and how this might help offset projected warming from climate change. My work spans the majority of topics treated in the recent text Urban Climates by Oke et al. (2017).
