Research interests

Chaotic dynamics are often described in terms of the “butterfly effect” where a minor change in the initialization of a model, tantamount to the flap of a butterfly wing, produces a radically different outcome over the course of a model run. My research interests lie primarily in the intersection of data, stability and prediction, to understand how dynamic instability impacts the uncertainty of predictive models. My postdoctoral appointment at NERSC is funded by the Reduced subspace in big data treatment: A new paradigm for efficient geophysical Data Assimilation (REDDA) project.
