Research Interests: (updated approx. mid-2015)
Dynamical systems and their applications to physical problems have been the unifying themes of my research. One of the areas of great interest to me is that of data assimilation - the incorporation of noisy observations of a system into an incomplete dynamical model of that system. This problem is pertinent to a variety of applications, including weather and climate prediction. I work on applications of Bayesian Markov Chain Monte Carlo (MCMC) sampling methods to data assimilation and on understanding the interplay between nonlinearity and statistics in these problems, and in particular, in the Lagrangian data assimilation problem.

My other research interests are in Hamiltonian systems, specially, periodic orbit bifurcation phenomena and breakup of invariant circles in nontwist systems, such as the meandering jet of the gulf stream in the Atlantic ocean, and applications of renormalization group methods in these problems.
