My research interest is mainly focused on Software engineering for AI (SE4AI). I am also interested in studying machine learning systems, software supply chain security, and trustworthy/responsible AI. My work adapts methods from studies on traditional software package registries (e.g., NPM, PyPI) to open-source pre-trained AI model (PTM) supply chain. I currently work on developing novel approaches to enhancing multiple aspects of the PTM supply chain , including trustworthiness, reusability, and security.
