I am an Assistant Scientist in the Department of Geology and Geophysics at the Woods Hole Oceanographic Institution. My work combines state-of-the-art statistical techniques and General Circulation Models (GCMs) with observed and paleoclimatic data to better understand climate dynamics on decadal-to-centennial timescales. My current research interests include the dynamics and characteristics of centennial timescale variability in the tropical Pacific, the dynamics and characteristics of decadal timescale drought, the physical processes underlying the simulation of drought by GCMs, and developing and employing spatiotemporal data analysis techniques. If you are interested in working in my lab as an undergraduate researcher, graduate student or postdoctoral researcher please reach out to discuss opportunities. I was previously at Columbia University for my doctorate and a postdoctoral scientist at the University of Colorado, Boulder and in the Advanced Study Program at the National Center for Atmospheric Research.
