Hi there! I am Hao Li (ζζ in Chinese), a third-year Ph.D. candidate in the School of Computer Science at Peking University, advised by Prof. Li Yuan. Before that, I got my Bachelor of Science degree in computer science at Peking University with a Summa Cum Laude.
My research interests include multimodal Learning, visual understanding, and AI for Chemical Science. I have published more than 20 papers at the top international AI conferences with total Google Scholar citations 800+.

Decoupled peak property learning for efficient and interpretable ECD spectra prediction
Hao Li, Da Long, Li Yuan, Yu Wang, Yonghong Tian, Xinchang Wang, Fanyang Mo
- Existing predictive approaches lack the consideration of ECD spectra due to the data scarcity, and the interpretability to achieve trust-worthy prediction. Here, we establish a large-scale dataset for Chiral Molecular ECD spectra (CMCDS) and propose ECDFormer for accurate and interpretable ECD spectra prediction. ECDFormer decomposes ECD spectra into peak entities, employs the QFormer architecture to learn peak properties, and renders peaks into spectra. Compared to spectra sequence prediction methods, our decoupled peak prediction approach substantially enhances both accuracy and efficiency, improving the peak symbol accuracy from 37.3% to 72.7% and decreasing the time cost from an average of 4.6 CPU hours to 1.5 seconds.
