## Biography

David B. Dahl is an Associate Professor in the Department of Statistics at Brigham Young University. He started his academic career at Texas A&M University as an Assistant Professor in 2004, was promoted with tenure in 2010, and moved to BYU in 2012. 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. During 2007-2012, Dr. Dahl was 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 interests are
Bayesian nonparametrics, model-based clustering, random partition models, protein structure prediction, bioinformatics, 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.
