About

Jung-Woo Choi is a leading researcher in acoustic signal processing, with a focus on sound localization and propagation in complex environments. His key research areas include diffraction-aware sound localization, non-line-of-sight (NLOS) audio sensing, and computational acoustics. Choi’s most notable contribution is his pioneering work on localizing sound sources that are hidden behind obstacles or barriers—a challenge that traditional line-of-sight methods cannot address. In his highly cited 2019 paper, "Diffraction-Aware Sound Localization for a Non-Line-of-Sight Source" (14 citations), he introduced a novel algorithm that exploits the diffraction properties of sound waves as they bend around objects. By integrating ray tracing-based sound propagation models with localization techniques, Choi’s approach enables accurate source detection in indoor environments where direct paths are blocked. This work has significant implications for applications in surveillance, robotics, and smart environments. With a growing citation impact, Choi continues to advance the field of acoustic sensing, pushing the boundaries of how sound can be used to perceive and navigate the physical world.
