Research Interests

My research interests revolve around sea-level changes over varying timescales from minutes to millennia, with a focus on coastal inundation from tsunami and storms, land-level changes due to megathrust earthquakes, climate-driven sea-level changes during the Common Era, and the mechanisms of long-term sea-level changes, including glacial isostatic adjustment. Within these areas, I have a strong interest in the comparison of geological data with predictions from models and from recent direct observations of land-level change and sea-level rise (e.g., GPS, tide gauges)
