The paleogeodesy and tsunami group employ both field-based methods (stratigraphic mapping, sediment descriptions, surveying) and laboratory-based methods (particle size, geochemical, and diatom analyses) to characterize coastal sedimentary sequences and identify evidence of sudden coseismic subsidence or uplift of the coastline and/or anomalous sand beds that may represent past tsunami inundation. Earthquake and tsunami chronologies are developed through radiocarbon, 137Cs, and OSL dating.

​The lab group is one of the only academic labs to specialize in diatom-based subduction zone paleogeodesy, an approach that is particularly valuable for quantifying coseismic land-level change across sharp stratigraphic contacts and identifying anomalous sand beds deposited by tsunamis over centennial and millennial timescales.
