I am an Associate Professor in Models and Methods for Clinical Psychology at Tilburg University (department of Methodology and Statistics). Currently, I hold a NWO innovational VENI grant, which was awarded to me for my “Network psychometrics” project proposal. From February-June 2017 I work as a fellow at the NIAS institute (Netherlands Institute for Advanced Study in the Humanities and Social Sciences).

My main interest concerns the development of conceptual and statistical models for the development and maintenance of psychiatric disorders such as major depression and generalized anxiety disorder. I specifically focus on network models and complex dynamical systems. From a network perspective, disorders develop because of prolonged direct interactions between symptoms. For example, insomnia causes fatigue, which, in turn, causes concentration problems and loss of interest; eventually resulting in a depressive episode. This conceptualization of disorders flies in the face of existing perspectives in which a depressive episode is a disease that – for example analogous to a lung tumor – causes its symptoms such as insomnia and fatigue.

Other interests include measurement invariance, item response theory (IRT), structural equation modeling (SEM), theories of measurement and solutions to the multiple comparisons problem.
