Research Physical Scientist

Affiliation:
+ NASA/Goddard Institute for Space Studies
+ Columbia University, Center for Climate Systems Research

Interests:
Climate modeling, Climate change, Abrupt climate change

Research Statement:
I am interested in the hydrologic cycle, and in particular tracers of the hydrologic cycle such as water isotopologues. These tracers are useful for establishing the provenance and (rainout) history of air parcels. They are also useful as a tracer of past climates (ice cores, cave deposits, ocean sediment cores, etc.). I do experiments with a general circulation model (the kind used in predicting future climate change) to discover details about the hydrologic cycle in the past and present in hopes of improving our ability to understand this part of the climate in the future.

Advises:
Graduate students; undergraduate students

Possible Student Projects:
+ Coupled climate model experiments including volcanic events
+ Modern distribution of water isotopologue tracers
+ Sea level rise and ice sheet health
+ Past Climate experiments; last ice age, last millennium, Eemian, Eocene, Holocene, deglacial, Heinrich events, 8.2 kya event
