Erkan Istanbulluoglu is a Professor of Civil and Environmental Engineering at the University of Washington. He studies the interactions among hydrologic, ecologic, and geomorphic processes in watersheds and how such interactions shape geohazards during climatic extremes. His research group develops and uses numerical models for landscape evolution, ecohydrology, landslide, debris flow and flood risk. These models are developed to study research questions that span time scales from long-term geomorphic phenomena, such as the evolution of gully networks and mountainous landscapes and their vegetation patterns, to engineering time scale predictions relevant to decision-making and design. His modeling interest also aims to develop models that can be rapidly implemented for near real-time hazard forecasts.
