On June 27th , 2025, Prof. U Jin Choi from KAIST gave a talk at the IBS Biomedical Mathematics Seminar. The title of his talk was “Simulation-Free Schrodinger Bridges Via Score and Flow Matching (by Tong et al, AISTATS 2024).”
On June 10th-13th, Dr. Shingo Gibo gave a poster presentation at the 2025 Hibernation Biology 2.0, Annual Meeting, which was held at the Okinawa Institute of Science and Technology (OIST) in Japan.
A recent study by BIMAG researchers has been featured in various Korean media outlets. This study proposes a novel method for efficiently and precisely estimating enzyme inhibition constants using only a single inhibitor concentration. The work was co-authored by undergraduate intern Hyeongjun Jang, Dr. Yunmin Song, and corresponding author Prof. Jae Kyoung Kim. The paper, titled “Optimizing enzyme inhibition analysis: precise estimation with a single inhibitor concentration,” was published in Nature Communications in June 2025. [Link to paper]
