I am the scientific director of ODISSEI (Open Data Infrastructure for Social Science and Economic Innovations), the national research infrastructure for the Dutch social sciences. In addition, I hold the chair in Social and Health Data Science at the department of methodology and statistics, Utrecht University. Our human data science group at Utrecht University applies data science and machine learning to scientific problems, especially in the social and health sciences. We also develop new methods that solve specific problems we encounter, often involving latent variable models.
