My research interests span physics-based simulations and data-driven approaches with deep learning as well as perceptual evaluation of simulations. I have been investigating more effective ways to simulate natural phenomena via utilization of refined data and to acquire reliable data for machine learning. Moreover, I have been studying human visual perception for not only computer graphics but also engineering applications while aiming for new evaluation approaches and better understanding of a variety of numerical methods.
I am working as a tenured assistant professor in the Computer Graphics group at Telecom Paris, France since Oct 2019. Before joining Telecom Paris, I worked as a postdoc at the Technical University of Munich with Nils Thuerey and Korea University from which I earned my Ph.D. in computer science and engineering under JungHyun Han’s supervision.
