Dr. Dongheon Lee from Professor Jung-Woo Choi’s research group will be appointed as an Assistant Professor in the Division of Electronic, Information and Communication Engineering at Pukyong National University, effective September 2026.
Dr. Lee earned his Ph.D. in February 2025, dedicating his research to artificial intelligence models for spatial acoustic analysis. During his doctoral studies, he conducted in-depth research on an integrated acoustic analysis system encompassing speech enhancement, sound source separation, noise reduction, direction-of-arrival estimation, and classification, utilizing spatial acoustic signals collected through multi-channel microphones.
In particular, he presented the “DeepASA” model at NeurIPS 2025, a unified spatial acoustic AI framework capable of comprehensively inferring all related tasks within a single model. In addition, he developed innovative multi-channel speech enhancement models and achieved outstanding research accomplishments by publishing a total of 12 first-author papers in leading conferences and journals in speech and audio, including ICASSP, INTERSPEECH, and IEEE Transactions on Audio, Speech, and Language Processing (TASLP). Furthermore, he demonstrated his practical technological expertise by leading his team to victory in DCASE Task 4, the 2025 international challenge on acoustic scene analysis.
We sincerely congratulate Dr. Dongheon Lee as he embarks on his career as an independent researcher. We wish him continued success in advancing the field of acoustic artificial intelligence and in emerging as a leading scholar in world-class research.
