I have a PhD in Computer Science from the University of Cambridge, UK. My research falls within the domain of human-computer interaction and involves using nonverbal behaviour cues and interaction context to interpret a user's affective state. I am also interested in studying social responses to affect-sensitive 'intelligent' machines and how they influence subsequent interaction and behaviour. I have a keen interest in the ethics of social computing, issues related to privacy and control and in general, responsibilities of technological change.
