Most of my research interests a related to answering important questions related to the environment. More specifically, I am interested in the analysis of massive spatial data sets; analysis of areal data, exploratory methods for identification of spatial structure, general spatio-temporal methodology; the use of hierarchical models to forecast wind speed, direction, wind farm power output; functional data analysis for large spatial and temporal data sets; dynamical systems for sptio-temporal data.

I actively collaborate with researchers from many departments at ISU, inlcuding Agronomy, Seed Science, Meteorology, Natural Resource Ecology and Management Ecology, Plant Pathology, Forestry, Entomology, Agricultural and Biosystems Engineering, Economics, Political Sciences, Civil Engineering, as well as from the grocery store chain HyVee, Iowa Soybean Association, MidAmerican Energy, Los Alamos and Pacific Norhtwestern National Labs.
