David B. Dahl

Biography

David B. Dahl is an Associate Professor in the Department of Statistics at Texas A&M University. He joined Texas A&M as an Assistant Professor in 2004 and was promoted with tenure in 2010. He did doctoral work at the University of Wisconsin -- Madison in the Department of Statistics and the Department of Biostatistics and Medical Informatics under the direction of Michael Newton, receiving his Ph.D. in 2004. He received B.S. and M.S. degrees from Brigham Young University in 1997 and 1998, working on his masters with Scott Grimshaw in the Department of Statistics. Since 2007, Dr. Dahl has also been an adjunct faculty member in the Division of Quantitative Sciences at the University of Texas, M.D. Anderson Cancer Center.

David B. Dahl's research focuses on Bayesian nonparametrics, model-based clustering, random partition models, and statistical computing. His work has appeared in journals including the Journal of the American Statistical Association, Annals of Applied Statistics, and Bayesian Analysis. He teaches both undergraduate and graduate classes, including Bayesian statistics, statistical methods, and statistical computing.
