Learning Interactions of Intrinsically Disordered Proteins (IDPs) with DNA
First Author | Advisor: Prof. Jian Ma | Ma Lab, CMU
- Developed the first deep learning approach to explore protein-DNA interactions for multiple IDPs.
- Achieved 0.84 Pearson correlation in efficiently predicting 20 kb base-resolution binding profiles using U-Net.
- Generalized across cell types with accuracy comparable to experimental reproducibility.
- Identified IDP-binding motifs and their spatial distribution, cooperative interactions, and binding preferences.
- Submitted a paper to RECOMB 2025.
- 2022.07 - 2023.05
Accelerating Molecular Dynamics Simulations of RNAs with a Graph Neural Network
Bachelor’s Thesis | Advisor: Prof. Jinjin Li | AIMS Lab, SJTU
- Developed a graph neural network (GNN) to predict molecular force fields for RNAs, achieving 8% relative loss.
- Integrated the GNN with a simulation tool to replace potential energy surface models for >1000× speedups.
- Improved the GNN's generalization ability through unsupervised data augmentation.
- 2022.05 - 2023.09
Predicting Molecular Properties with a Rotationally Invariant Graph Neural Network
First Author | Advisor: Prof. Jinjin Li | AIMS Lab, SJTU
- Designed a graph neural network (RotNet) with a rotationally invariant transformation, overcoming the generalization deficiency caused by rotations of molecules.
- Generalized well to various molecular conformations and achieved 2% relative loss, outperforming prior state-of-the-art methods.
- 2021.10 - 2022.09
Predicting Protein Energy Changes upon Single-Point Amino Acid Mutations
First Author | Advisor: Prof. Jinjin Li | AIMS Lab, SJTU
- Designed the Clustered Tree Regression (CTR) method, integrating unsupervised and supervised learning.
- Achieved a 6% improvement in accuracy compared to previous methods, using protein sequences alone as input.
- Developed software for CTR with copyright license No. 2022SR1040914 granted in China.
