My research interests are, broadly: interdisciplinary mathematical/stochastic modeling, data assimilation, Monte Carlo sampling, reduced
order modeling. Specifically: numerical methods for data assimilation and inverse problems – importance/implicit sampling, Markov chain Monte
Carlo, variational methods, Kalman filters.
I create new mathematics and computational tools and work towards their successful application across the Earth sciences. A main theme of my work is how sampling methods can function (or not) in high-dimensional spaces.
