Axel Mayer obtained his PhD in 2013 from the University of Jena, Germany. In 2014–2016, he was a post-doctoral researcher in the Department of Data Analysis at Ghent University, and in 2016-2020 he was Juniorprofessor at the Department of Psychology, RWTH Aachen University. Currently, he is a professor for Psychological Methods and Evaluation at Bielefeld University. Since 2018, he is president of the European Association of Methodology.

In his research, he is interested in developing new methods for investigating if, how, and for whom an intervention, such as a psychotherapeutic treatment or a health training, has an effect. His methodological research emphasis is on development and application of models for analyzing average and conditional (causal) effects, causal mediation models and models for latent change. An important aspect of his research is the development of user-friendly statistical software, to make modern statistical methods and models available for a broader audience.
