Peter Arnold, a native Coloradan, studied environmental design and physics at CU Boulder and earned his M.Arch. at SCI-Arc. He has taught design and geospatial research studios at Woodbury and UCLA, and has photographed the infrastructural landscapes of the west extensively. Current research includes analytic modeling and visualization of ephemeral stream systems in arid rural environments; the analysis of embedded energy within imported water supplies in the urbanized west; and the quantification of stormwater as groundwater augmentation supply. ALI's co-founder, Peter serves as Director for Research. He has led ALI's GIS lab since inception and advised numerous thesis projects.
