I am interested in studying tropical and extra-tropical climate variability on decadal to millennial timescales. To understand climate variability and study its impact on environment, ecosystems and landscape, I use a suite of approaches that hinges on exploiting 'proxy observation' in high-resolution natural archives (e.g. corals, well-dated lacustrine materials).  I am also interested in using proxy-based climate information to help inform agricultural and business decisions that require knowledge of long term regional climate variability.

I also study earth, climate and ocean process that operate on timescales of millions of years and leave signatures in fossil and the sediment record. I use high precision techniques (such as ion probe, electron probe, clumped isotope and trace elements) in well-preserved fossils and carbonate veins to look for remnants of ancient oceans by constrain effects of diagenesis that often affects these old materials.
