To be decided


My research is focused on understanding the modern climate system and reconstructing past climate variability using biological, chemical, and physical archives of climate and environmental change found in lake sediments. My ultimate goal is to place recent climate change in a deeper and broader context to improve our projections of future climate change.

I develop and use records of environmental change in the Galápagos and the Tibetan Plateau to understand past variability in the Intertropical Convergence Zone, the El Niño/Southern Oscillation, teleconnections between western North America drought and the tropical Pacific, Asian monsoon precipitation, and dust variability on interannual to millennial timescales. I also focus intently on analyzing large gridded datasets of variables such as precipitation and sea surface temperature to understand modern spatiotemporal variability in these climate fields.

Additionally, I investigate the modern tropical Pacific hydrologic cycle. I am presently dissecting the relationship between climate and the stable isotopic composition of both rainfall and seawater in the tropical Pacific using observations and general circulation models in order to improve our interpretations of water-isotope based paleoclimate proxies such as corals, speleothems, and sediment records.

I am currently looking for postdocs, undergrads and graduate students to join the lab. Contact me via email if you are interested.
