Welcome to the Department of Statistics at Colorado State University. Statistics is the science of inferring knowledge from data and describing uncertainty in those inferences. It plays a central role in scientific research, social policy, and governance. The Department of Statistics has a world-class record of success in education, research and service and has an out-sized impact on campus because of its engagement in educating students in all disciplines and interdisciplinary research.

Three Statistics PhD Students Present Research at CSU GRADSHOW
Statistics PhD Students, Danielle Demateis, Seongwon Im, and Troy Wixson, presented their research at the 2022 Graduate Student Showcase (GRADSHOW). Danielle’s work, titled “Distributed Lag Interaction Model: Birth Weight and Air Pollution”, studies the effect of air pollution exposure during pregnancy on birth weight. Seongwon’s work, titled “Tree Distributed Lag Mixture Model for Zero-inflated Count Data: Estimating the impact of Wildfire smoke and COVID-19 on mortality in Colorado”, studies the exposure and interaction effects of wildfire smoke and COVID-19 on mortality. Troy’s work, “Attribution of Seasonal Wildfire Risk to Changes in Climate”, models the extreme seasonal risk of wildfire and studies the fire weather observed in the Grand Lake area of Colorado in 2020. Statistics Associate Professor, Ander Wilson, served as a judge on the Awards Committee.
Danielle, Seongwon, and Troy enjoyed presenting at the GRADSHOW, because it was good practice to explain their work to people from different disciplines at both high and low levels of detail. Also, they commented that the GRADSHOW provided an opportunity for them to connect with peers and faculty across departments at CSU, which may lead to collaborations and helps them see how statistics is used across campus.

Undergraduate Summer Research
This summer 10 Statistics and Data Science undergraduates gained valuable experience by participating in research projects. More than 30 students applied for paid positions sponsored by the College of Natural Sciences and the Statistics department. Students were supervised by faculty members Haonan Wang, Josh Keller, Ben Prytherch and Ann Hess. Statistical methods included data wrangling, visualization, linear and logistic regression, mixed models, principal components analysis, type M errors and simulation. Students presented their work to the department on June 30. They will submit posters to Celebrate Undergraduate Research and Creativity (CURC) in Spring 2023.
