I am an Assistant Professor in the Graduate School of Data Science at Seoul National University, directing Causality Lab . Prior to joining Seoul National University, I was an Associate Research Scientist at Columbia University and Postdoctoral Research Associate at Computer Science, Purdue University working with Prof. Elias Bareinboim. I got my Ph.D. in College of Information Sciences and Technology, Pennsylvania State University, University Park, under the supervision of Prof. Vasant Honavar.
Currently, I am working on the theory and application of causality from the perspectives of machine learning, artificial intelligence, and data science. In particular, I am interested in causal discovery, sequential decision-making, and the identifiability and estimation of causal effects in diverse settings. During my Ph.D. study, I focused on causal discovery in a relational domain.[CV]
Research Interests
- Causal Inference (how can we identify and estimate the effect of an intervention?), Causal Decision Making (how can we utilize causal information in decision making?), Causal Discovery (how can we establish causal relationships from complex data?)
- (Future) Developing theories and applications for health and social domains with causality as a first principle. Developing robust machine learning models and algorithms utilizing causal knowledge. Artificial general intelligence and causality (how can an agent equip a causal mindset. how to counterfactually reason about its actions and consequences.)
