We investigate climate variability in the past, present, and future using a variety of tools, including paleoclimate proxy records, modern climate observations, and climate model simulations.
Our current research projects include:
-Understanding the atmospheric and oceanic processes recorded in the stable oxygen isotopic composition of precipitation, seawater and vapor. This includes long-term investigations in the Galápagos and Palau as well as global-scale analyses.
-Reconstructing past climate variability of the central tropical Pacific with stable isotopes of fossil ostracodes in the Kiritimati lagoon
-Understanding the nature of large-scale atmospheric circulation in the past using paleowind direction proxies and paleodata-model comparisons
-Assessing trends and variability in modern wind speeds and directions with station data and climate reanalyses
