Brandon M. Greenwell, PhD

Director of Data Science @ 84.51° | Adjunct @ University of Cincinnati

Google Scholar | LinkedIn


Hi there! I'm Brandon, a statistician turned machine learning practitioner and tools developer. I bridge the gap between theoretical statistical foundations and scalable, production-grade AI. Currently a part of the AI Enablement team at 84.51° (Kroger's data science arm) and teaching graduate-level stats and analytics.

When I'm not training models or teaching, I'm building high-performance developer tooling in Rust and Go, or writing and maintaining statistical packages in R.


Highlights

  • Work: Designing enterprise-grade foundational AI/ML tooling, libraries, and patterns for the Kroger ecosystem.
  • Books: Author of Hands-On Machine Learning with R and Tree-Based Methods for Statistical Learning in R.
  • Open source: Active maintainer and contributor to highly-cited R packages (e.g., fastshap, pdp, vip) and modern CLI/terminal utilities in Rust and Go.

Featured open-source projects
