Computational biostatistics, machine learning, precision medicine

I’m a postdoc in Chris Holmes’ research group interested in the development and application of statistical methods for replicable scientific discovery in biomedicine. The data we focus on are typically complex and high-dimensional, comprising a combination of genetic, molecular and clinical data collected in large cohorts. Some methodological areas of current interest include Bayesian sparse factor models, ensemble methods in multi-view learning, and identification of responder subgroups in clinical trials.
