Short CV

I'm an assistant professor at the Methodology and Statistics unit of Psychology, with a focus on (advancing) research integrity, open science, meta science, and transparency for the improvement of (psychological) science. I work on theory and implementation of methodologies and practices that make science more transparent and self-correcting, such as replication, preregistration, and large-scale team efforts. 

I am a community manager for the Open Science Community Leiden, and chair of the Dutch network of Open Science Communities (OSC-NL: https://www.osc-nl.com/).

The courses I teach include Good Research Practices, Responsible Research in Practice, fMRI Data and Statistics, and Scientific Conduct for PhD students.

I am actively involved in open science and scientific integrity initiatives and policy-making, and conduct meta-scientific and scientometric studies in this area. I was one of the first researchers in psychology to publish a Registered Report, I co-founded the Open Science Community Leiden, and serve on the board of the national network of Open Science Communities. I have acted as an editor at Collabra: Psychology, contributed to the Ethics Committee of the Psychological Science Accelerator (a global lab network), and as member of the Code of Conduct Committee of the Society for Improvement of Psychological Science (SIPS) and national events like the Open Science festival.

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 Exploratory Report in Cortex).
