David is a physical geographer with interdisciplinary research interests focusing on three complementary themes within hydroclimatology (interface between hydrology-climatology): (1) hydroclimatological processes within alpine, Arctic, mountain and glacierized river basins; (2) climate and river flow regimes; and (3) river energy budget and water temperature dynamics. He has cross-cutting interests in ecohydrology/ hydroecology, specifically ecological response to hydro-climatological and physico-chemical habitat variability/ change, and development of new methods for monitoring, analysing and modelling environmental dynamics
