I am a JSPS gaitoku postdoctoral researcher at The University of Tokyo, working with Takeo Igarashi. My research focus on human-guided optimization, where I explore combinations between different human priors and numerical optimization and develop supportive system for visual content design. I did my Ph.D. in the computer graphics group at CMLab, National Taiwan University, advised by Bing-Yu Chen. I got my B.S. and M.S. degree in Information Management, both from National Taiwan University. During my M.S. period, I worked in the computer graphics group of CMLab with Bing-Yu Chen and Yung-Yu Chuang. After that, I have been a research assistant at the Multimedia Computing Lab with Wen-Huang Cheng, and Imager Lab with Alla Sheffer. Also, I have been a visiting researcher at the Igarashi Lab at the University of Tokyo with Takeo Igarashi.
