Data drives most of my statistical omics research: provide a generic, robust solution for a given study, and one likely solves similar problems for many studies. My research interests cover a wide spectrum, including high-dimensional data analysis (omics) and predictive modeling, incl. machine learning. My main fascination nowadays is omics-based clinical prediction and classification, by either statistical or machine learners. Here, I focus on developing methods to improve predictive performance and biomarker selection by structural use of complementary data (co-data), e.g. from external studies or data bases. Moreover, we develop tools to aid interpretation of ML, e.g. by providing inference for variable importance metrics. We directly apply and test such methods in a number of collaborative projects on cancer diagnostics and prognostics.

We want our methods to be used, so we implemented these in R-packages, which include data, example(s) and documentation. Group packages.
Together with Wessel van Wieringen, I teach High-Dimensional Data Analysis in the Statistical Science Master, Leiden. Topics involve: regularized regression, multiple testing, shrinkage, empirical Bayes, analysis of high-dimensional count data. I also contribute to the Biostatistics course to medicine students in the research master Personalized medicine.
