Tidewater glaciers, those that terminate in the ocean, are strongly influenced by processes that occur at the glacier-ocean boundary. Iceberg calving and submarine melting remove ice and also influence glacier geometry and flow speeds, while deposition of sediment at glacier termini provides some flow resistance and protects glaciers from calving and melting. The couplings between these processes and glacier dynamics lead to nonlinearities that can cause tidewater glaciers to undergo rapid changes in volume and be out-of-phase with climate. 

My research focuses on understanding the dynamics of tidewater glacier boundaries and implications for glacier evolution.
