I am a broadly trained stable isotope geochemist with a primary focus on climate and environmental reconstructions from continental archives including lake sediments and tree-rings at different time-scales of the Quaternary. 
I am currently serving as a Program Director of the paleoclimate Program at the National Science Foundation.
