I am interested in analyzing data observed on spatial and temporal domains, and the theoretical, methodological, and computational issues that commonly arise in environmental and meteorological applications with large datasets. My research is grounded in the spectral theory of random fields, which often provides concise characterizations of statistical models for spatial-temporal data and leads to computationally efficient methodology.
We are always looking for opportunities to collaborate with scientists on exciting applications. Currently, we have an ongoing project with Dean Hesterberg and Matt Polizzotto in Soil Science at NC State, who are interested in understanding the reactivity of toxic trace elements in soil and have collected rich datasets on elemental composition of sand grains at spatial scales of 10 micrometers or smaller.
