The Department has a long history of research and collaborations in Environmental Statistics and in Spatial Statistics, beginning with Jim Zidek's pioneering work with the United States Environmental Protection Agency. Since that time, faculty have been involved in many research projects, such as the development of statistical techniques for the analysis of air pollution data to study concerns such as public health issues and global climate models.  Current work modelling air pollution has resulted in the an interactive map for the World Health Organization, developed by an international team of researchers.   Other recent research activities involve collaboration with marine mammal biologists, to study locations and behavior via continuous-time tracking devices.
