Portfolio

Andreas Brandmaier is head of the Formal Methods in Lifespan Psychology project at the Max Planck Institute for Human Development in Berlin, Germany. He is also a fellow of the Max Planck UCL Centre for Computational Psychiatry and Ageing Research.

Dr. Brandmaier promotes conceptual and methodological innovation within developmental psychology and in interdisciplinary context. Particularly, he develops methods and computational tools to answer methodological challenges of lifespan psychology. His primary research interests are interindividual differences in behavioral and neural development, brain-behavior relations across the lifespan, and the adaption of datamining and machine learning approaches to challenges of psychological research.

Andreas is interested in exploratory 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. Dr. Brandmaier's recent research has been published in Science, Psychological Bulletin, Psychological Methods, Psychology and Aging, Developmental Psychology, Frontiers in Psychology, Neuroscience, and NeuroImage. In 2015, Andreas Brandmaier won the Heinz-Billing-Award for outstanding contributions to Computational Science.
