My research interests lie in active tectonics and in intricately related topics such as past sea level and glacial isostatic adjustment, which bear on questions of tectonic deformation at timescales from centuries to millennia. Broadly, my work involves applications of neotectonics, paleoseismology, and paleogeodesy to address fundamental questions of earthquake hazard, earthquake recurrence and repeatability, fault segmentation, fault interactions, and past sea-level change.
Many of my studies involve the use of coral microatolls to infer past changes in relative sea level, which we can use to infer past land-level change, glacial isostatic adjustment, and tectonic deformation. I have ongoing research using coral microatolls in Singapore, Malaysia, Indonesia, and the Philippines. I am also building a research program in Myanmar involving terrestrial paleoseismology to quantify deformation and assess hazard across the complex plate boundary there.
I am a geologist by training, but I collaborate extensively with the Geodesy Group at EOS, in order to apply geodetic modeling techniques to more rigorously interpret the geological data that we collect. I also collaborate extensively with the Coastal Lab and Sea Level Research groups. For more details, see my group webpage.
