*Title: Modelling Mental Illnesses: Multiplexes to Rescue? *Abstract: Understanding mental illnesses requires looking at a variety of different factors contributing to the development, persistence, and treatment of mental illness. That is, scientists must take into account the role of, e.g., behavioral, psychological, neurophysiological, genetic, pharmacological and environmental influences on psychopathology. To integrate real-world data regarding such varied factors, complex computational models have been raising high hopes. In this talk, I shall examine the vices and virtues of recent multiplex approaches for grasping psychopathology. *Keywords: mental illness, mental disorder, multiplex, causal graph, symptom network model, connectivity *Speaker: Lena Kästner is professor for philosophy, computer science and artificial intelligence at University of Bayreuth, Germany. Previously, she has been an assistant professor in philosophy of science at Tilburg University in the Netherlands and a junior professor in philosophy of mind and cognitive systems at Saarland University, Germany. Her background is in cognitive science and cognitive neuroscience and she holds a PhD in philosophy. Her primary research areas are philosophy of mind and philosophy of science, especially philosophy of cognitive science. She works on scientific explanations, causation, scientific discovery and experimentation, psychopathology, and explainable AI (XAI). Currently, Prof. Kästner is head-PI of the project “Explainable Intelligent Systems” (www.eis.science).
