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.
I am a faculty mentor for the Math Alliance, a nationwide effort to make sure that every student from an under represented or underserved community with an interest in mathematics has the opportunity and the necessary tools to earn a doctoral degree. You can write to me directly about opportunities within Math Alliance or go to my mentor page.
