I'm a Scientist at the Computational Social Cognition group, Institute of High Performance Computing, A*STAR, Singapore. 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 where I've 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 have experience designing serious games. We designed a suite of tablet-based 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.
