Personal Summary

My research focus is in Computational Landscape Ecology: Developing, optimizing, and applying simulation programs for understanding relationships between biological processes and population patterns across landscapes. I am also part of UM's Center for Population Health Research and pursuing work to improve air pollution exposure models and the modeling of factors that influence respiratory health, specifically for rural populations like Montana.
