Research
We are developing modern machine-learning approaches for analyzing massive biomedical data to better understand disease mechanisms and deriving actionable insights. There are two main streams in our research. One is algorithm development. We are looking into various aspects of developing effective biomedical machine-learning models, such as multimodal learning, federated learning, model interpretability and explainability, algorithmic fairness, causal inference, etc. The other is application, where we apply the algorithms developed to help with real-world biomedical problems, such as disease risk prediction, disease subtyping, computational drug repurposing, clinical trial emulation, etc.
Current Projects:
- Predictive modeling of clinical risks
- Disease subtyping
- Computational drug discovery and design
- Knowledge graph
- Clinical trial emulation with real world data
