## Summary  
Achim Zeileis is an Austrian statistician and university professor who specializes in statistical computing, econometrics, and machine‑learning methods. He is best known for his research on R‑based statistical software and for teaching statistics at the University of Innsbruck.

## Biography  
- **Born:** 1975  
- **Education:** Technical University of Dortmund (Ph.D. – doctoral advisors Walter Krämer and Kurt Hornik)  
- **Known for:** Development of statistical methods and R packages for econometrics, time‑series analysis, and machine learning  
- **Employer(s):** University of Innsbruck (Professor of Statistics); former faculty at TU Wien (2000 – 2003)  
- **Field(s):** Statistics, statistical software (R), machine learning, econometrics, psychometrics, weather forecasting, probability theory  

## Contributions  
Achim Zeileis has authored a large body of peer‑reviewed research covering statistical methodology, econometrics, and machine‑learning applications. His work frequently appears in leading journals and conference proceedings, and he is a prolific contributor to the R ecosystem, creating and maintaining packages that enable robust regression, time‑series handling, and sandwich‑type variance estimators. These tools are widely adopted by researchers in economics, meteorology, and the social sciences, facilitating reproducible analysis and advanced modeling. Zeileis’s publications on heteroskedasticity‑consistent covariance matrix estimation and on visualizing statistical models have become standard references, cited thousands of times. Through his teaching at the University of Innsbruck and earlier at TU Wien, he has supervised numerous doctoral students, spreading modern statistical computing practices across Europe.
