Bio Statement

Brian P. Hobbs, Ph.D., holds the academic appointment of Assistant Professor in the Department of Biostatistics at The University of Texas MD Anderson Cancer Center (MDACC) in Houston, Texas. His recent publications have established methodological frameworks for facilitating various scientific applications: design and implementation of randomized multi-arm screening platforms, group sequential design based on time-to-treatment failure and total toxicity burden as co-primary endpoints, Bayesian predictive approaches for personalized treatment selection, integrative analysis of voxel-wise imaging features and genetics, and classification of multivariate spatially interdependent collections of correlated features. Methods from several of Dr. Hobbs’s publications have been translated into user-friendly software ( providing tools for data analysis, design, and conduct of adaptive trials. Through multidisciplinary collaboration with investigators at MDACC, he’s further contributed to the biomedical sciences, predominately in areas related to cancer imaging as well as through implementation of systematic reviews and meta-analyses.

Dr. Hobbs completed his undergraduate education at The University of Iowa. As a graduate student at The University of Minnesota, he completed an internship in biostatistics at Mayo Clinic in Rochester, Minnesota. Thereafter, he obtained a master’s and doctoral degree in biostatistics at The University of Minnesota in Minneapolis. The International Biometric Society, ENAR, recognized his thesis work, bestowing on him the John Van Ryzin Award of 2010 for best paper submitted to the Eastern North American Region (ENAR) distinguished student paper award competition. Dr. Hobbs completed a postdoctoral fellowship in the Department of Biostatistics at MD Anderson Cancer Center before joining the faculty in 2011. In February 2016, he was selected by The University of Minnesota for the Emerging Leader Award, an honor bestowed upon alumni on the basis of impactful contributions within 10 years of graduating from one of the School of Public Health’s programs.
