Research Interests
My general research interests include time series analysis, spatial statistics, stochastic processes and their applications, robust statistics, extreme value theory, and financial mathematics. The focus of recent research is model fitting and prediction for nonlinear, non-Gaussian processes observed over space and time. This work has applications in the areas of economics and finance, the geosciences, and signal processing.
