I am a Visiting Scientist at the NTU-Alibaba Joint Research Institute, Singapore. My research interests lie mainly in Computational Narrative Intelligence and related computer vision and NLP problems.

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.

In order to understand the complex artifact that we call a story, it is necessary to jointly employ multiple AI capabilities to construct meaning from the ground up. To this end, I also spend time on multimodal reasoning and the machinery of deep neural networks.

From 2017 to 2019, I was a Senior Research Scientist at Baidu Research USA. From 2015 to 2017, I was a Research Scientist at Disney Research, leading a group of postdocs and interns. Prior to that, I worked as a postdoc with Leon Sigal and Jill Lehman. In 2014, I obtained my Ph.D. degree from Georgia Institute of Technology, working with Mark Riedl.
