Hi, I'm Katie (Caitlin R. R. Turner), a postdoctoral researcher at the Institute of Arctic and Alpine Research (INSTAAR) at the University of Colorado Boulder. I study how water moves through coastal and estuarine systems and how extreme flood events shape the environments downstream. My current NSF-funded project focuses on Juneau, Alaska, where I'm investigating how repeated glacial outburst floods, and the levees built to contain them, reshape the Mendenhall-Juneau estuary. Across my work, I combine numerical modeling with statistical machine learning, and I develop open-source software and models so that others can build on them. My earlier research examined how large-scale freshwater flow events influence coastal ecosystems, including toxic cyanobacteria blooms in Louisiana and water exposure times in semi-enclosed estuaries.
