Research Interests

My research focuses on statistical models and methods for spatial and spatial-temporal processes. In particular, I am interested in the nature of the spatial-temporal interactions implied by these models and on developing statistical methods for assessing these interactions.

My main motivation for studying spatial-temporal processes is to describe variations in the physical environment. Some of the processes my collaborators and I are currently studying include stratospheric ozone, air pollution at both regional and urban scales, and sediment transport in the Great Lakes. One of our goals is to incorporate the information from deterministic physical models into the statistical modeling of these processes in order to evaluate and improve the physical models and to provide better predictions of spatial-temporal processes than can be obtained from either purely statistical or purely deterministic approaches. Another current interest is in statistical approaches to processing large environmental data sets into forms that can be readily used by numerical modelers such as climate modelers.
