TAEKYUNG KI

I am a researcher at KAIST MLAI working on generative models and computer vision.

Bio: From March 2022 to March 2025, I was a researcher working on video generation as an alternative military service in South Korea. I started researching deep learning in February 2021. I received M.S in mathematics in February 2021, and B.S. in mathematics in February 2019.

I am interested in the following research topics:

Generative models (score-based and flow-based models, etc.)
3D Gaussian splatting and neural implicit representation
Human video generation
Human motion representation
Audio-visual and Vision-language representation

If you have an interest in the above research topics, feel free to drop me an e-mail.
