Short CV

As an assistant professor at the Methodology and Statistics unit Dr. Anna van ‘t Veer focuses on improving the process of psychological research, in all stages of the research cycle. She received her psychology BA and MA from Leiden University, and her PhD from Tilburg University (Social Psychology, Tilburg Institute for Behavioral Economic Research), where she studied moral psychology. During her time as a PhD-student, she developed a special interest in improving the way researchers practice science; why and how should researchers preregister their studies? How can experimental designs be optimized in order to learn as much as possible? How are replications best performed? And how do daily research choices relate to principles of transparancy and Open Science? After receiving her PhD, she accepted a postdoc position at Leiden University studying neurobiology of fatherhood. From this time on, she has also been actively involved in the development and improvement of scan-protocols and analysis pipelines for the MRI facilities of the Leiden Institute for Brain and Cognition (LIBC). Dr. van ‘t Veer serves, amongst other things, as an advisory board member for Curate Science, and contributes to the Ethics Committee of the Psychological Science Accelerator (PSA), she is an editor at Collabra: Psychology.


Dr. Anna van ‘t Veer’s research focuses on developing and improving methods that are used in psychological science. Keywords are (promoting) open science, meta science, research integrity and transparency. She is actively involved in open science initiatives, resulting in publications on replication and pre-registration and collaborations with other experts in this area. With this network, she has published about models for large-scale collaborations to enhance scientific value, and she has conducted such large-scale projects. Current projects involve research integrity and estimating which of many original findings is are most valuable to put our replication efforts towards (see SIPS 2019 prestudy poster).


Dr. Anna van ‘t Veer teaches courses in the bachelor's programmes of Psychology (e.g., Good Research Practices, Perspective on Career Planning), in the (research) master's programmes of Psychology (e.g., Responsible Research in Practice, fMRI Data and Statistics), and in the Graduate School for Social Sciences (Scientific Conduct for PhD's and Postdocs).
