Matthew W Bryan, Ph.D.

Dr. Bryan’s statistical research focuses on longitudinal methods for comparing rates of change. This methodology can be applied to many scientific areas, including studies of childhood growth, clinical trials with longitudinally measured outcomes, and tumor growth. For example, these methods were used to evaluate the possible association between early antibiotic exposure and weight gain in children. Other areas of research interest include methodology for multivariate longitudinal data and non-parametric smooth function estimation via penalized splines. His collaborative work focuses on studies in pediatrics and, in particular, on studies of infant growth, infectious disease, and mental health. He is a faculty member of the Pediatrics Biostatistics Section within the Division of Biostatistics, which centers on collaborations at the Children’s Hospital of Philadelphia (CHOP). He joined the biostatistics faculty in August 2013.
