Professor Allan's research focuses on freshwater systems with particular emphasis on streams and rivers. His work in community ecology includes studies of predator-prey interactions, the downstream transport or drift of aquatic insects, and studies of invertebrate distribution and abundance. Current research examines the influence of land use and landscape settings on the ecological status of streams and rivers, flow variability and its influence on the biological community, and indicators of stream ecosystem conditions. The common theme in these projects is the intent to develop a better understanding of the land-water linkages that influence stream ecosystems function in human-altered drainage basins. He served on the board of American Rivers and was, for six years, Chair of the Science and Technical Committee.
