A Bit About Me

John is a Principal Data Scientist for Cybersecurity and Enterprise Technology at MassMutual, where he built and leads the company's cybersecurity data science program. He created its first in-house cybersecurity machine learning models and now leads the shift to agentic AI, defending the enterprise at machine speed.

His work includes CATCH, MassMutual's primary user and entity behavior analytics tool, which factors into roughly 40% of confirmed detections while outperforming commercial tooling. He now leads SPARTA, a program for autonomous zero-day discovery and patching, and is modernizing security operations and the software development lifecycle with agentic workflows.

Before MassMutual, John earned his PhD in Computer Science from the University of Vermont and co-founded the UVM–MITRE Computational Finance Laboratory. His research on U.S. equity market microstructure was featured in the Wall Street Journal and led to a new DARPA program and an SEC contract at MITRE.

Working remotely from Vermont, John races in the International Lightning Class sailing circuit and spends his off hours on woodworking and photography, all with the backdrop of the Green Mountains.
