I'm a Human-Computer Interaction Scientist at Callaghan Innovation. Callaghan Innovation is New Zealand government's Crown Entity that provides research and technical services, and funding to local businesses, to help them grow. I'm part of the Assisted Devices team at Callaghan. We work towards providing technical solutions for assisted living in a variety of medical conditions.
My research interests include Human-Computer Interaction, Socially Intelligent Systems, and Language Technology, inspired by theories in Linguistics, Cognitive Science, Social Psychology.
I did my PhD in Natural Language Generation for Spoken Dialogue Systems on “Generating Politeness for Conversational Systems Aimed to Teach English as a Second Language” from the Department of Computer Science, University of Sheffield, UK in 2009. I built a conversational system that generates dialogues with appropriate level of politeness according to the context.
After my PhD, I moved to Singapore I was a Scientist at the Computational Social Cognition group of IHPC, A*STAR, Singapore. In Singapore I worked on a variety of research projects. Related to politeness, is the notion of deception. I investigated verbal deception techniques people use for manipulating each other's beliefs. I also designed tablet-based serious games for detecting early onset of Alzheimer's disease in the elderly population. In addition to these, I have researched and modeled the psychological process of how people form first impressions. I have also contributed to studies aimed at better understanding human decision making. You can read more about my projects, and publications.
