Méhu studied Psychology at the University of Liège (Belgium) with specializations in Cognitive-Behavioral Therapy and Ethology. After two ethnological field studies on non-human primate behavior in South India and West Africa (Republic of Guinea), he completed a Ph.D. in Evolutionary Psychology and Behavioral Ecology at the University of Liverpool in 2007. Méhu's doctoral thesis investigated the function of smiling and laughter in social interactions.

In the final years of his Ph.D., he spent several months as a visiting researcher at the (former) Ludwig-Boltzmann-Institute for Urban Ethology, hosted by the Department of Anthropology at the University of Vienna. He then moved to the University of Geneva for a postdoctoral position at the Swiss Center for Affective Sciences. Méhu was appointed Assistant Professor of Psychology at Webster Vienna in October 2013 and was promoted to Associate Professor of Psychology in January 2019. 

Research interests

Méhu's main interests lie in the study of affective phenomena and social behavior from an evolutionary perspective. In particular, he is interested in the role of emotion and nonverbal behavior in competitive and cooperative social interactions. In 2004, he became a certified coder of the Facial Action Coding System (FACS) and has used it extensively in his research.

As a member of the Social Signal Processing Network (SSPNet), he also has a great interest in the automatic analysis of communicative behavior and in Affective Computing. More recently, he has moved towards applying his research to the fields of negotiation, political communication, and clinical psychology.

Méhu is currently involved in several research projects in relation to nonverbal communication, emotion, and social interaction:

- Negotiation and Emotion (NEMO): An interdisciplinary project on individual differences in socio-emotional skills in relation to dyadic negotiation.

- Analysis of facial, vocal, and bodily cues in naturally occurring social interactions (political debates) with a focus on the expression of agreement, disagreement, and dominance.

- The role of cognitive appraisal bias in the generation and maintenance of emotional disorders.

Gernot Gerger

Dr. Gernot Gerger

Post-Doctoral Researcher


  • PSYC 2825 Introduction to Research Methods
  • PSYC 3625 Topics in Psychology: Motivation and Emotion

Gerger conducted his master studies (finished 04.2006) in Psychology at the Faculty of Psychology, University of Vienna, Austria. He also finished the pre-clinical part of Medicine (University of Vienna) reflecting his research interests and specializations in Biological Psychology. In his master thesis, he researched memory phenomena with the help of EEG (electroencephalography). Following this, Gernot completed his doctoral studies (10.2006-05.2011) and first post-doctoral position (09.2011 – 08.2017) at the Empirical Visual Aesthetics Lab (Faculty of Psychology, University of Vienna, Austria) in the field of Empirical Aesthetics.

In this second main research field, Gerger was mainly interested in how the complex interplay of emotions and cognitions contributes to (aesthetic) judgments. In order to more fully understand this interplay, he combined various methods by including psychophysiological measures (e.g, facial electromyography;  eye-tracking, skin conductance responses) in concert with explicit judgments and behavioral measures in the laboratory as well as field studies. In May 2018 he started his second post-doctoral position at Webster Vienna as a researcher for an FWF funded project (I3645) awarded to Dr. Marc Mehu. The projects try to uncover implicit prejudice and discrimination in inter-group relations in both field and laboratory studies.

Research interests
