General information

[top] [fold]

I am a postdoctoral researcher at ETH Zürich (Switzerland) since March 2014, with Markus Gross at CGL, and am currently visiting the BeingThere Centre at NTU Singapore.

I conduct research in the fields of Computer Vision and Computer Graphics. My current research focuses on understanding and manipulating scene appearance. In particular, I have developed methods for separating material colors from the effects of the illumination in a photograph (TVCG 2013, ICCV 2015, TOG 2015), for transferring lighting across images of a photo collection (SIGGRAPH Asia 2012), and for recognizing and editing high-level scene properties in photographs of outdoor scenes (SIGGRAPH 2014).

I was previously a postdoctoral researcher at Brown University, working with James Hays. I did my Ph.D. in the REVES team at Inria Sophia-Antipolis (France), under the supervision of George Drettakis and Adrien Bousseau. I defended my thesis entitled "Intrinsic Image Decomposition from Multiple Photographs" on October 12, 2012. During my PhD, I visited Boston to work with Frédo Durand (MIT) and Sylvain Paris (Adobe), and Berkeley to work with Maneesh Agrawala. Before joining Inria, I received M.Eng. and M.Sc. degrees from INSA Lyon in France and was an exchange student at KAIST in South Korea. I did some research on content-aware image retargeting with Sung-Eui Yoon, Christian Wolf and Khalid Idrissi, and worked on catadioptric vision with Jean-Charles Bazin and Inso Kweon.
