PTM Naming: Why “What’s in a Name” Actually Matters for AI Reuse
- 27 December 2025
I’m thrilled to share some recent work led by Wenxin Jiang, a PhD student at Purdue University. Wenxin is supervised by James C. Davis, and I have had the pleasure of serving as a key external supervisor and PhD committee member on this project as part of my ongoing collaboration with Dr. Davis. This research was recently accepted for publication in Journal of Empirical Software Engineering and it tackles a problem that anyone working in AI has likely grumbled about: how we name our models.

Special Issue on Low-Code/No-Code + Metaverse in IEEE Computer
- 23 February 2025
Low-code/no-code is increasingly converging with the metaverse to reshape how we create and experience technology. As AI-driven tools automate significant portions of coding and power immersive virtual environments, organizations can achieve new efficiencies—provided that security, ethics, and user empowerment remain central.
TLA+ for All: Running Model Checking in a Python Notebook
- 05 February 2025
TLA+ has long been a powerful tool for designing and verifying complex systems. However, many students and practitioners have felt excluded by the ecosystem’s complexity, the need to install multiple tools, or the misconception that formal methods are only for specialists. This project aims to change that.
A Signal Injection Attack Against Zero Involvement Pairing and Authentication for the Internet of Things
- 28 December 2024
Zero Involvement Pairing and Authentication (ZIPA) is a technique for automatically provisioning large networks of Internet-of-Things (IoT) devices with no user involvement. Prior ZIPA work generally assumes that the environment used for pairing is sufficiently isolated from external, adversarial signals. In our DESTION 2024 paper (see Citation below), we present the first signal-injection attack capable of influencing ZIPA-based key generation, demonstrating that these assumptions can fail in realistic settings.
AI in Hiring: Fairness or Just Automated Bias?
- 18 November 2024
Artificial intelligence has become increasingly embedded in modern hiring systems. From résumé screening to candidate scoring, automated tools promise efficiency, objectivity, and scale. Yet these promises often obscure important risks: when AI models inherit biased historical data, they can reinforce or even amplify inequities in hiring.
