Statistics Building

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.


Department Highlights

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.

College Early Career Award for Dr. Josh Keller

The College of Natural Science has awarded Dr. Josh Keller with its prestigious Early Career Teaching and Mentoring Award.  An Assistant Professor in the Department of Statistics, Dr. Keller was recognized for his remarkable record of course innovation and development, his leadership in inclusive excellence, and his exemplary mentorship of graduate and undergraduate students in their research endeavors. The Department of Statistics is grateful for Dr. Keller’s dedication and commitment to excellence in education and mentorship, and congratulates him for this well-deserved recognition.

Welcome to the '22-'23 Academic Year!

The Statistics Department is excited about the start of the ’22-’23 academic year.  The Department welcomed 12 new students into its MS/PhD program, added a new class in the Master’s of Applied Statistics Program, and met our new Statistics Undergraduates at Ram Welcome.  Classes start Monday, August 23. Welcome to all the new Rams!

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.

Addison D. Adams Joins the Institute for Defense Analyses

ALEXANDRIA, VA (June 2022) – Colorado State University student Addison D. Adams joined the Institute for Defense Analyses (IDA) as a summer associate in the Operational Evaluation Division of IDA’s Systems and Analyses Center. Adams is a graduate student at Colorado State working towards his doctoral degree in statistics. He earned his bachelor’s degree in mathematics from Utah Valley University in 2019. IDA is a nonprofit corporation that operates three federally funded research and development
centers in the public interest. IDA answers the most challenging U.S. security and science policy questions with objective analysis leveraging extraordinary scientific, technical and analytic expertise.

Dr. Julia Sharp named a Fellow of the American Statistical Association

Dr. Julia Sharp was recently named a Fellow of the American Statistical Association for excellent and sustained collaboration that advances the development and practice of statistics, for exceptional mentoring and teaching of statisticians and researchers using statistical methods, and unparalleled service to the ASA and profession.

The designation of ASA Fellow has been a significant honor for nearly 100 years. Under ASA bylaws, the Committee on Fellows can elect up to one-third of one percent of the total association membership as fellows each year.

To be selected, nominees must have an established reputation and have made outstanding contributions to statistical science. The Committee on Fellows evaluates each candidate’s contributions to the advancement of statistical science and places due weight on the following:

  • Published works
  • Position held with employer
  • ASA activities
  • Membership and accomplishments in other societies
  • Professional activities

Dr. Bailey Fosdick Discusses Colorado COVID-19 Surge with Media

Dr. Fosdick was recently interviewed by 9news ( and CBS Denver ( about her work with the Colorado School of Public Health COVID-19 Modeling Team. As COVID-19 cases and hospitalizations sharply rise in Colorado, modeling the future of the pandemic in the state has proven to be more and more challenging.


American Society of Agronomy Honors Group of Statisticians

Julia Sharp, along with a group of other statisticians, will be recognized with The American Society of Agronomy Presidential Award. The Presidential Award is given to “…an individual or group that has impacted our society members in a substantive and lasting way…. (Volenec, ASA President).” The award proclamation states: “The American Society of Agronomy Presidential Award is given to individuals or teams who have influenced agronomic science or crop production practices so greatly that the impact of their efforts will be enduring on future science. This year’s award goes to the NCCC-170 and Experiment Station Statisticians. This group’s contributions has taken many forms including: statistical courses in classrooms; one-on-one guidance on specific research problems; resolution of statistical issues surfaced during the peer-review process; convening popular workshops; authoring key books on emerging statistical methods; and participation in and improving grant applications. They have guided ASA members through decades of change in statistical analyses starting with punch cards and SAS and ending with clouds and R. Most importantly, our science, the evidence underpinning our conclusions and recommendations, and the students we have educated are better because of their scholarly contributions.” A representative from the group will receive the award at the 2021 ASA, CSSA, SSSA International Meeting in November.

Congratulations to MAS almun JD Drumheller!

JD Drumheller was named one of the winners in the 2021 ASA Statistics and Environment Section’s data challenge! His winning project was titled: “Predicting tree species distributions in Colorado forests using climate models.” JD graduated from the MAS Data Science program in the summer of 2021. Congratulations JD!
