Research Engineer

Youngjun Choi is a second-year PhD student at TX Lab, KAIST, advised by Prof. Jinjoon Lee. His research focuses on the intersection of aesthetics and human-computer interaction, particularly in the theme of landscape, AI and multisensory experiences. He’s interested in enriching the discourse on how digital interfaces can be leveraged to create immersive exhibitions, thereby expanding the boundaries of artistic expression and audience engagement.


Participated in the exhibition ‘Audible Garden’ as a creative developer responsible for algorithmic composition and sound design. He developed a novel data sonification and visualization framework that transcodes physical objects into multisensory outputs. This interdisciplinary approach has also been the subject of academic output, with the work being submitted to Leonardo | MIT Press, as the first author (currently under review).

Micro-variation of Sound Objects Using Component Separation and Diffusion Models

Choi, Y., Liu, P., & Lee. J. Micro-variation of Sound Objects Using Component Separation and Diffusion Models. ICMC. 2023.
Introduced a novel method for resynthesizing sound objects using component separation techniques and deep neural networks called diffusion models. It offers a unique approach to achieving sophisticated, non-deterministic variations in sound characteristics, enhancing digital sound design and music composition. This innovative technique opens up new possibilities for artists and engineers in creating rich, varied soundscapes and patterns. This work was presented at the International Computer Music Conference (ICMC) 2023 as co-first author.

Cartography of Urban Ambience

Conducted an speculative practice of merging map-making with environmental sound analysis, underscoring the integration of multimedia analysis on cartography. It effectively captures the identity of urban environments, arousing further curiosity about different districts by imagining the ambience through colors. He has submitted this work as the first author of a full paper to the International Symposium of Electronic Arts (ISEA) 2024 (currently under review).
