I am a senior research scientist at School of Computing and Information Systems, Singapore Management University. Previously, I lead a research team at Living Analytics Research Centre in the Smart Consumption and Healthy Lifestyle application domain where we are developing personalized healthy eating and behavioral change technology for just-in-time behavioral change interventions.

My research interests include the applications of data mining, natural language processing, and machine learning techniques in digital health and well-being domains, especially food consumption and health, personal informatics and quantified self, crowdsourcing, and computational social science in general.
