Thomas Fuchs, MD, PhD, is Karl Jaspers Professor of Philosophy and Psychiatry at Heidelberg University, Germany. His main areas of expertise include phenomenological philosophy and psychopathology as well as embodied and enactive cognitive science, with a particular emphasis on non-representational, interactive concepts of social cognition. He was Coordinator and Principal Investigator of several large national and international grants, among them the European Research Training Network Towards an Embodied Science of Intersubjectivity (TESIS, 2011-2016). He has authored over 300 journal articles, book chapters and several books. He is also co-editor of Psychopathology and editorial board member of 4 scientific journals.

Thomas Fuchs' Ecology of the Brain has taken up the challenge by pulling together under one cover a circular causality framework, an increasingly detailed description of what an embodied subjectivity implies, and in doing so, the possibility to apply these perspectives to different disciplinary fields and to inspire further research and conceptual scrutiny.
