Robert B. Gramacy Professor of Statistics
Biography
I am a Professor of Statistics in the College of Science at Virginia Polytechnic and State University (Virginia Tech/VT) and affiliate faculty in VT's Computational Modeling and Data Analytics program. Previously I was an Associate Professor of Econometrics and Statistics at the Booth School of Business, and a fellow of the Computation Institute at The University of Chicago. My research interests include Bayesian modeling methodology, statistical computing, Monte Carlo inference, nonparametric regression, sequential design, and optimization under uncertainty.
Latest News
- In 2023 I began work on an NSF project forecasting phytoplankton blooms for drinking water quality.
- As of Jan 1 2023, I am Editor-in-Chief of Technometrics.
- In 2022 I received an Outstanding Service Award from the ASA Section on Physical and Engineering Sciences.
- In 2022 I began work on an NSF project studying local Gaussian processes for jumps in engineering systems.
Research
The papers listed on the right are chosen to represent my current research interests. I’ve lately been very excited about large scale computer model emulation for calibration and optimization.
