I am a Nanyang Associate Professor at the School of Computer Science and Engineering, Nanyang Technological University, Singapore. My research interests lie mainly in Computational Narrative Intelligence, Multi-modal Learning, and Machine Learning.

Prior to NTU, I was a Senior Research Scientist at Baidu Research USA, and a Research Scientist and Group Leader at Disney Research. I received my Ph.D. degree from Georgia Institute of Technology.

Story is a powerful tool for communication, an exhibit of creativity, and a timeless form of entertainment. Computational Narrative Intelligence (CNI) aims to create intelligent machines that can understand and create stories, manage interactive narratives, and respond appropriately to stories told to them. I have made contributions to all major areas of CNI, ranging from story generation and interactive narratives to human cognition, from learning story knowledge to story understanding.

I believe that in order to simulate human intelligence, artificial intelligence must first acquire human-level knowledge from an approximation of the human experience, which is inherently multimodal. Further, inspired by the observation that human intelligence emerges from the interaction of multiple cognitive processes, I am interested in understanding the interactions between different neural network components and developing techniques that coordinate the learning of different neural network components beyond simplistic stochastic gradient descent.
