Johannes Textor is an associate professor at Radboud University, where his research bridges bioinformatics, causal inference, and computational biology. He leads the development of software tools like DAGitty, widely used for causal diagram analysis. Textor's research focuses on developing computational methods to understand biological processes, particularly in immunology and epidemiology. He also explores theoretical questions in causal inference, helping to clarify how cause-and-effect relationships can be identified from data.
