Research Interests

I study the transfer of sediment through riverine and coastal environment, as well as short-timescale depositional histories (fortnightly to centennial timescales). Much of this work is centered in the Arctic and sub-Arctic, where environmental conditions are rapidly changing, driving changes in how sediments are dispersed through fluvial systems and deposited and reworked on continental shelves.

Research and Activities

My lab conducts field work (often by boat and in remote places) to measure hydrodynamic and sedimentary processes (using common oceanographic instrumentation); conducts lab analyses of physical samples (e.g., grain-size and radiochemical analyses); and performs data analyses of time-series datasets – as well as some sediment transport and morphodynamic modeling.
