I am a Professor of Statistical Science at Duke University and have served as Chair of the Department of Statistical Science at Duke since 2013. I received my PhD in 1993 from the University of Minnesota and joined the faculty at the Institute of Statistics and Decision Sciences (now the Department of Statistical Sciences) at Duke University in the fall of 1993. I am a past President of the International Society of Bayesian Analysis (ISBA), and an elected Fellow of ISBA and the American Statistical Association. My research focuses on Bayesian solutions to the related problems of feature/variable selection, model selection and prediction using an ensemble of models to account for model uncertainty using Bayesian Model Averaging, with an emphasis on prior choice and computation.
I have developed several R packages to support research in BMA, including BAS , Bayesian Adaptive Sampling for Bayesian Model Averaging. My work is inspired by applications in environmental health, chemistry, genomics, neuroscience and astronomy, among others.
In my free time, I enjoy time with my family, sailing , puttering in the garden, growing orchids, photography, and exploring the Durham food scene and cooking!
BAS version 1.2.0 was released on CRAN today. This version corrects a bug that would lead to corruption of data using the byte compiler; we recommend that all users upgrade as soon as possible. Other features include using BAS in simple linear regression, to obtain BF or posterior probabilities for...
BAS version 1.1.0 introduces a truncated Beta-Binomial Prior distribution on the number of predictors included in a model, which is useful for the case. This corresponds to a Bernoulli prior on the inclusion indicators with a common parameter inclusion probability , and in turn is assigned a Beta prior distribution...

The Duke University Board of Trustees Saturday approved six new graduate degree programs that will be offered in 2014. The new master’s degrees are in bioethics and science policy, historical and cultural visualization, medical physics, statistical science and economics and computation. The board also approved a new Ph.D. program in...
