Associate Professor and Undergraduate Chair, Department of Statistics, Penn State University

Office: 421D Thomas

Phone: 814-863-8126

I received my M.S. and Ph.D. from the School of Statistics at the University of Minnesota and a B.S. in computer science (with minors in statistics, mathematics and film) from Carnegie Mellon University. I was a postdoctoral fellow at NISS (courtesy appointment at Duke University) (2003--2004) and a New Research Fellow at SAMSI (2009--2010). I spent my sabbatical (2011--2012) at the Department of Statistics, University of Washington.

Primary Research Interests

For more on my research, Ph.D. students etc. please see background and research.

- Statistical computing, primarily Markov chain Monte Carlo algorithms
- Models for spatial data: Gaussian random field models, Bayesian hierarchical models
- Complex computer models/computer experiments: statistical emulation and calibration
- Cross-disciplinary research in environmental sciences: climate science, disease modeling, ecology
