Through multidisciplinary work I attempt to improve our understanding of the functioning of the immune system in a quantitative manner. We use mathematical modeling and bioinformatics to find mechanistic and quantitative interpretations of the typically complex data obtained in the laboratories of close collaborators. In our collaborative work these interpretations typically for new questions and novel experiments.

There is a strong focus on estimating the expected life span and interdivision times of various populations of T cells in the immune system to better understand their population dynamics. This requires the development of appropriate mathematical models for rigorous interpretation of data delivered by the various types of labeling techniques used by immunologists (BrdU, deuterium, and CFSE), and provides new insights into the formation of acute immune responses, and the maintenance of long-lived immune memory by short-lived cells.

A second focus is on the modeling and analysis of in vivo multi-photon microscopy data. The visualization of the dynamic behavior of and interactions between immune cells using time-lapse video microscopy has an important role in modern immunology. To draw robust conclusions, quantification of such cell migration is required. We analyze videos of individual cells migrating through tissues and interacting with other cell types, to quantify the migratory properties of the cells, their search times, and their conjugation times with others. We make 3-dimensional models of cells migrating through tissues to test whether our estimated migratory properties deliver the observed behavior, and to test our analysis tools on in silica data.

A recent development is the development of a bioinformatic pipeline to analyze deep sequencing data from T cell repertoires (with Arno Andeweg, Rotterdam), and the analysis of cellular barcode data to quantify the heterogeneity in primary and secondary immune responses (with Ton Schumacher, Amsterdam). Finally, agent based models are used for studying evolutionary questions in silico, and for two-level immuno-epidemiological models combining within-host immunity with massive between-host heterogeneity due to MHC polymorphisms.
