I grew up in central China, in a small city of Hubei Province by the Yangtze river. I received my undergraduate training at Beijing University, majoring in logic and philosophy. After I got my BA, I went to Carnegie Mellon University to pursue a PhD, initially hoping to become a mathematical logician. However, a course titled Probability and Artificial Intelligence shifted my academic interest, from formal deductive systems to inductive logic, epistemology, and methodology. I ended up writing a dissertation on causal reasoning, which has multiple points of contact with not only philosophy but also other disciplines such as computer science, psychology, and statistics.
My main research interests remain interdisciplinary to this day. The key questions that motivate my primary research program concern the extent to which information about cause and effect can be reliably inferred from passive observations (as opposed to active experiments), and the extent to which such inferred causal information can effectively guide predictions and decision-making. The attempts to address these questions are usually logical, epistemological, or even algorithmic in nature, but they are also related to important issues in the metaphysics of causation. I am grateful to the Research Grants Council of Hong Kong for having funded several of my projects in this research program, ranging from epistemological examinations of causal inference to the bearings of causal reasoning on decision theory. The research findings from these projects were published both in premier journals of philosophy and in leading venues of artificial intelligence and machine learning.
I taught previously at California Institute of Technology, Lingnan University, and Hong Kong Baptist University. While teaching in the Department of Religion and Philosophy at the Hong Kong Baptist University, I was also affiliated with the Ethical and Theoretical AI Lab and the Centre for Applied Ethics, and developed an interest in some issues of AI ethics, especially those that may be illuminated by causal modelling, such as algorithmic fairness and explainability.
