Hyelin Nam
I'm a PhD Student in Computer Science and Engineering at the University of Michigan , where I'm advised by Prof. JJ Park . Before that, I completed my master's at KAIST , where I was advised by Prof. Jong Chul Ye .
I am interested in video generative models and world models , exploiting their controllability to better capture physically plausible dynamics in generated videos.
I am open to research internships for Summer 2027 and collaborations . Feel free to reach out!
