David J. Allan is Professor Emeritus at the School of Natural Resources & Environment, at the University of Michigan. His work emphasizes the application of ecological knowledge to species conservation and ecosystem management. Research interests center on the influence of human activities on the condition of rivers and their watersheds, including the effects of land use on stream health, assessment of variation in flow regime, and estimation of nutrient loads and budgets. Additional, collaborative activities are directed at the translation of aquatic science into useful products for management, conservation, and restoration of running waters.
He has authored many publications and multiple books, including the previous editions of Stream Ecology published by Springer.
