I am a Research Engineer at Socket where I work on software/AI supply chain security. I obtained my Ph.D. from ECE@Purdue in May 2025 where I was supervised by Prof. James C. Davis. My research interest is mainly focused on Software/AI Supply Chain Security and Software engineering for AI (SE4AI).

My doctoral thesis is titled “Trustworthy Reuse in the Machine Learning Model Supply Chain”. I am also interested in studying machine learning systems, software supply chain security, and trustworthy/responsible AI. My work adapted methods from studies on traditional software package registries (e.g., NPM, PyPI) to open-source pre-trained AI model (PTM) supply chain. –>

My work has been mostly published at software engineering venues (ICSE, FSE, ASE, ISSTA, EMSE, ESEM, MSR), and security venues (CCS, SCORED).

I am the recipient of the Estus H. and Vashti L. Magoon Research Excellence Award in 2025!

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