Fields of interest: 
Analyses of climate fields based on historical, instrumental and paleoclimatic data; El Nino and Southern Oscillation; ocean data assimilation; statistical studies of climate variability from observations and models

I work in the Climate Modeling Group which is part of the LDEO Division of Ocean and Climate Physics. My research is on climate variability, predictability, and prediction, and on methods to study such things. It involves historical climate analyses, paleoclimatic reconstructions, data assimilation, and studies of error dynamics in the ocean and coupled climate models.
