Research interests

In my research, I investigate the behavioural and brain mechanisms of our rich and diverse social lives. From how we communicate our emotions to why we won’t help during an emergency when other people are present. To that goal, I use neuroimaging, brain stimulation, behavioural measures, and virtual reality. Recently, I have begun to integrate this work with recent developments in social robotics, to study interactions with artificial agents, such as social robots. Why do we at one time perceive a robot as a simple machine, while at other times as an engaging social being? Ultimately, my goal is to integrate these two topics even further to study social interactions in a technology-rich world, that is humans interacting with other humans with or without the use of technology.
