Dr. Vallacher directs the Dynamical Social Psychology Lab in the Psychology Department. He is also a Research Associate in the Center for Complex Systems, University of Warsaw, Poland, and a Research Affiliate in the Advanced Consortium on Cooperation, Conflict, and Complexity at Columbia University. He has authored or edited 8 professional books and written over 100 book chapters and journal articles. Dr. Vallacher has presented the results of his research in over 150 national and international conferences, and has delivered invited addresses at over 20 universities in the United States and Europe. He has been a Visiting Scholar at University of Texas at Austin; University of Bern, Switzerland; Max Planck Institute for Psychological Research in Munich, Germany; and University of Montpellier, France. In recent years, Dr. Vallacher and his colleagues at Columbia University, University of Southern California, Groningen University (the Netherlands), and Warsaw University (Poland) have adapted principles and methods from complexity science and nonlinear dynamical systems to investigate a wide range of topics in personality and social psychology, including self-concept, self-regulation, mindfulness, social judgment, close relationships, stereotyping and prejudice, sport psychology, social change, and intergroup and international conflict.
