The Department of Statistics and Data Science Bi-Annual Newsletter, Fall 2025

Introduction from Xuming He

As we enter the third year of our young department, there is so much we want to share with you in this newsletter.

We are enthusiastically expanding our statistics and data science curriculum for our students. They now have access to a range of new courses that prepare them well for the digital age. We are enhancing our research mentoring for students, including a summer undergraduate research program [page 2] and optional master’s theses. This fall, we welcomed a strong cohort of PhD students [page 24] who are excited to pursue their academic dreams with us.

The department now boasts over 20 tenure-track faculty, three teaching faculty, and seven postdoctoral fellows. Together, they have significantly expanded both our research and teaching capacities. Our latest faculty recruits are highly promising young scholars specializing in the foundations of machine learning and artificial intelligence, causal inference, and Bayesian statistics.

I am very proud of what our faculty is achieving. Dr. Likai Chen was promoted to Associate Professor with tenure. Several of our faculty members received new research grants from the National Science Foundation [page 8]. Our presence in the global statistical community is evident through the recent editorial appointments of our senior faculty [page 9]. I hope this newsletter provides you with another snapshot of who we are and what we are doing.

Our Graduate Programs

Professor José E. Figueroa-López and Professor Nan Lin share updates about our Graduate programs

Xiaofeng Shao, Professor of Statistics & Data Science and Professor of Economics

This past July, Shao attended the International Conference on Machine Learning (ICML) in Vancouver- his first machine learning conference. He shared, “It was an eye-opening experience to see the scale and energy of that community. It left me with the sense that AI-inspired research will keep pushing statistics and data science in exciting directions for many years to come. Right now, I am really excited about how statistics and machine learning are coming together. Technologies like ChatGPT have opened up whole new areas and research problems for statisticians and data scientists, and you can feel the pace of the field accelerating, especially with the surge of submissions to machine learning conferences. “

Mengxin (Maxine) Yu, Assistant Professor of Statistics & Data Science

The introduction of AI has created new research opportunities for statisticians- exciting opportunities, if you ask Professor Yu. “For example, how can we ensure that outputs from AI systems are trustworthy, and how can statistical tools help prevent hallucinations while better understanding AI behavior? I am also excited about the interdisciplinary role that statistics and data science play in solving real-world problems, spanning medicine, science, and engineering.”

Undergraduate Programs

Director of Undergraduate Study, Joe Guiness, along with the Undergraduate Curriculum Committee, is working to create new programming for their undergraduate students

  • This course gives students real world practical experience with analyzing data.
    SDS 3111 focuses on learning linear regression.

When Alexander graduated from WashU with a BA in Statistics in Spring 2025, he had already secured a position as a Business Analyst at Red Ventures.

About his interview strategy, Popolow shared, “I emphasized my strengths and made sure that I came across as a strong learner and easily coachable.” As a Statistics & Data Science student at WashU, he learned about delving into and understanding data. He shared that it’s one thing to learn about statistics from a textbook, but his time in the department taught him how to read and understand data. This has helped him dive into his new role at Red Ventures- already understanding the ways in which different metrics relate to one another and why they’re important.
