After Charles Efferson received a Ph.D. in evolutionary ecology at the University of California, Davis, he had post-doctoral positions at the Santa Fe Institute in New Mexico and at the Institute for Empirical Research in Economics at the University of Zurich.  Before coming to the University of Lausanne, Charles was also a Senior Research Associate in the Economics Department at the University of Zurich, followed by a period as Lecturer in the Psychology Department at Royal Holloway, University of London.

Charles' research focuses on the gene-culture coevolution of human social cognition and behavior in domains involving conformity, coordination, and cooperation.  He routinely mixes evolutionary modeling with the analysis of both experimental and observational data.  Charles has conducted fieldwork in Europe, Western Asia, Africa, and South America.  Much of his current empirical research examines the mechanisms underlying socially harmful cultural traditions like female genital cutting and the preferential abortion of females.  This research typically involves the evaluation of strategies for reversing such harmful traditions, and accordingly Charles has collaborated extensively with UNICEF, the World Bank, and various NGOs. 

Among other journals, Charles has published in Evolution and Human Behavior, Nature Human Behaviour, Proceedings of the Royal Society B, Proceedings of the National Academy of Sciences, Science, and Nature.  He is consulting editor for Evolution and Human Behavior and a member of the editorial board for Evolutionary Human Sciences.

Managerial Decision Making and Negotiations – EMBA (2006-2013)

Julian Marewski (Full Professor) is a cognitive and decision scientist, interested in understanding what strategies people use to solve decision problems and which ones could help them to make better decisions. As decision processes cut across disciplinary boundaries, so do his research and teaching interests.

Currently, he is interested in simple, actionable rules for leadership and other ill-structured inter-personal tasks in applied real-world settings. He examines the usage of such rules in various modern-day professional (e.g., in business, medicine, aviation), historical (e.g., ancient Roman military settings), and societal (e.g., sects) contexts. 

Research. In general, Marewski is interested in how and when particularly simple strategies, dubbed heuristics or simple rules of thumb, can aid making clever decisions in different domains. A central theme of his inter-disciplinary work is how the interplay between strategies and the environment shapes performance and behavior. Tackling this question often requires studying (i) the structure of environments and (ii) how decisional processes depend on components of cognition that are key for perceiving and/or representing the environment (e.g., memory).  For instance, Marewski has modeled how people select between decision strategies as a function of how memory nestles into the structure of informational environments. In so doing, he has asked when people use strategies that exploit memory retrieval processes (e.g., retrieval fluency, recognition). To give another example, he has been interested in how social environments can lead people to perform seemingly unethical acts.

Further areas of interest can be inferred via his publications. They range from human intuition and rationality to medical decision making, specific rules of thumb (e.g., the recognition heuristic), statistical inference, (e.g., Chimpanzee) memory, or research evaluation, with a unifying question of his cross-disciplinary interests being how agents make decisions in their environments.

Marewski's research makes use of a variety of tools and data (e.g., experiments, field data, web frequency data, computer simulation methods). For instance, while historical sources and interviews with experienced professionals inform some of his current interests, he has conducted computer simulations and laboratory experiments to understand how people select among the decision strategies in their repertoire, working with detailed computational models of cognition (i.e., the ACT-R cognitive architecture).

Marewski's work has been published in Psychological Review, the Journal of Management, Scientometrics, Conservation Biology and other outlets. He has acted as ad hoc reviewer for several international funding agencies and scientific journals in different disciplines. His work has been funded, for instance, by the Swiss National Science Foundation. He is an Associate Editor for the journal Frontiers in Research Metrics and Analytics (Section Research Methods). He has been on the editorial board of the Journal of Applied Research in Memory and Cognition, and acted as guest editor for that journal as well as for Judgment and Decision Making and the Journal of Behavioral Decision Making.

Teaching. Marewski teaches at the Executive (EMBA, MBA, CAS, in-company), PhD, Master, and Bachelor-level. For example, he has taught statistics, data analytics and quantitative methods for management, as well as courses on leadership, organizational behavior, and soft-skills and his teaching portfolio also includes cognitive psychology. Furthermore, Marewski trains specialized audiences (e.g., managers, doctors) on topics such as decisional leadership, medical decision making, risk-communication (e.g., in health care), or data ethics and data risks (e.g., in business). In many of his courses, Marewski uses the case method of teaching.

Christian Zehnder holds a PhD in Economics from the University of Zurich. He is Professor of Organizational Decision Making and Vice-Dean for Faculty. His research is interdisciplinary in that it combines insights from Economics, Psychology and Management and builds on various methodological approaches including laboratory experiments, field experiments and game theoretic models. Christian Zehnder is interested in understanding the behavioral drivers of decision making in organizations. His recent work focuses on two central topics in organizational research: conflict management and employee motivation. He has written a series of articles showing that the use of simple and seemingly overrigid contracts can help to diminish conflicts and counterproductive work behaviors. Most recently he became interested in studying the impact of charismatic leadership on employee performance in various organizational environments.
