I am interested in blending observations, theory and numerical models in order to understand, simulate and predict the ocean circulation. Until recently, I worked primarily with the Modular Ocean Model, MOM4, and was a co-developer of the latest version in the more than 35 year lineage of this model. I am also a contributor to the Flexible Modeling System, FMS, which serves as the backbone of the MOM4 infrastructure and allows us to couple to a variety of atmosphere, ice and land model components. The family of FMS models has been recently extended to include the GOLD layer model. Much of my present research is directed towards this model, although I still have active projects using MOM4.
