About Me

I am a Senior Engineer at Qualcomm AI Research in Korea. I received my Ph.D in Artificial Intelligence from Korea Advanced Institute of Science and Technology (KAIST) under the supervision of Professor Jaegul Choo. My research interests include image & video generation, image-to-image translation, and data scarcity problems. In particular, I am interested in developing deep learning models for virtual try-on, head reenactment, hairstyle transfer, and long-tailed learning. Recently, I focus on developing algorithms to personalize the foundation models for real-world applications.
