I am an assistant professor at the School of Electrical Engineering (Computer division) at KAIST (Korea Advanced Institute of Science and Technology). My research interests include Database-Artificial Intelligence (DB-AI) Integration, Big Data Analytics, and Big Data Systems. Prior to KAIST, I was a Research Scientist at Google Research working on data infrastructure for TensorFlow Extended (Google's large-scale machine learning platform). Before Google, I was a Ph.D. student and Postdoctoral Researcher at the Computer Science Department of Stanford University. I was a member of the Stanford InfoLab working with Professor Hector Garcia-Molina. Here is my CV (updated May 2019).
