About me

I am currently a Ph.D. student candidate (Dec, 2023) at ECE@Purdue. I am supervised by Prof. James Davis.

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.

Here is a list of projects that I am actively working on:

  • Trustworthiness: Anomaly detection for PTM naming and architectural defects.
  • Reusability: PTM recommendation system considering engineering requirements.
  • Security: Defense against Pickle deserialization vulnerabilities in PTMs.

My work has been published at ISSTA’24, ESEM’24, MSR’24, ICSE’23, MSR’23, ESEC/FSE’22, ASE’22, SCORED’22, and EMSE.

I am also the leader of Purdue’s Pre-Trained Models in Deep Learning VIP team (previously TensorFlow Model Garden VIP team where we collaborated with Google).
