Welcome!

Welcome to my web site! I am a Physical Oceanographer/Climate Scientist at Los Alamos National Laboratory (LANL), and an Affiliate Research Professor at the International Arctic Research Center (IARC) of the University of Alaska Fairbanks (UAF). My research interests span a wide range of topics, but generally concern the dynamics of the large-scale ocean circulation, and the ocean's role in the climate system.

About me...

I am PI of DOE's HiLAT-RASM project, which is a collaboration between scientists from LANL and Pacific Northwest National Laboratory (PNNL), and several academic partners. Our team is highly interdisciplinary, and we are investigating feedbacks and impacts of high-latitude climate change.

From 2009 to 2013 I was a part-time research affiliate at the New Mexico Consortium, working on an NSF-funded project to study decadal variability in the North Pacific.

Before coming to Los Alamos I was a postdoc in the group of Sarah Gille at Scripps Institution of Oceanography (2003-2005). There I studied the response of the Southern Ocean to high-frequency wind forcing. My study of topographically trapped barotropic modes started my fascination with the Argentine Basin.

From 1999 through 2002 I was a postdoc in Henk Dijkstra’s group at the Institute for Marine and Atmospheric Research Utrecht (IMAU). With Henk I worked on the application of fully-implicit solvers to the stability and variability of the global overturning circulation, using concepts from Dynamical Systems Theory.

I received my PhD in Physical Oceanography in 2000 from Utrecht University. For my PhD research I worked with Will de Ruijter to study the impact of interbasin exchange -in particular, Agulhas Leakage- on the Atlantic Meridional Overturning Circulation.
