I am an experimental social psychologist seeking to understand the psychology of communication, social interaction, and emotion. There is an evolutionary and cultural evolution theoretical basis underlying my research. I use methods drawn from the affective computing and behaviour oriented artificial intelligence domains. I try to understand these issues using technology to observe and quantify behaviour. Recent topics of study include emotion, laughter, empathy, and gossip, and the methods employed include VR, physiological sensing, and face and body behavioural analysis.
