Andreas Brandmaier is a Professor for Research Methodology at the Department of Psychology at the MSB Medical School Berlin. He is also a senior research scientist in the Formal Methods in Lifespan Psychology project at the Max Planck Institute for Human Development in Berlin, Germany, and a fellow of the Max Planck UCL Centre for Computational Psychiatry and Ageing Research.
I promote conceptual and methodological innovation within lifespan psychology and in interdisciplinary context. Particularly, I develop research methods and computational tools to answer methodological challenges of psychology inquiry. My primary research interests are interindividual differences in behavioral and neural development across the lifespan, the adaption of datamining and machine learning approaches to challenges of psychological research, reproducibility, and Open Science.
I am interested in statistical methods to better explain interindividual differences in change such as SEM trees and forests combining structural equation modeling and decision trees; finding alternative and optimal study designs when planning empirical longitudinal studies; and modeling the emergence of individuality and its relationship to brain plasticity. My research has been published in Science, Psychological Bulletin, Psychological Methods, Psychometrika, Psychology and Aging, Developmental Psychology, Frontiers in Psychology, Neuroscience, NeuroImage, and Cerebral Cortex. In 2015, I was awarded the Heinz-Billing-Award for outstanding contributions to Computational Science. I am an editor of Quantitative and Computational Methods in the Behavioral Sciences.
