Biography

I am an assistant professor of statistics at Colorado State University. Along with teaching statistics classes, I also work in the Department of Biology at Colorado State University, doing research with the Dr. Joe von Fischer lab.  I completed my PhD in the Department of Statistics at Colorado State University under the advisement of Dr. Jennifer Hoeting. My primary research interests lie in spatial, Bayesian, and non-parametric statistics applied to ecological, environmental, and biological problems. My current research is funded by the Environmental Defense Fund, and I am involved in their project to locate natural gas leaks and quantify their methane emissions. In the past I have been funded by the STATMOS research network. In addition to my research, I am also interested in statistics education, and I enjoy sharing and learning new ways to teach statistics.
