Background
I'm an AI security founder and policy-oriented engineer focused on idea security: how meaning moves through humans, models, and workflows, and how organizations can enforce boundaries when language models make it easy to transform and transmit knowledge.
I graduated from the United States Military Academy at West Point ('16) with dual degrees in Computer Science and Mathematical Sciences. Early on, I built machine-learning systems for strategy games and worked on applied ML research in communications systems.
In the U.S. Army, I served in operational and technical roles, including leading teams in cyber-relevant missions and advising senior commanders. That experience shaped how I think about real-world constraints: uncertainty, adversaries, and the need for systems that work under pressure.
I graduated from the Harvard Kennedy School Master in Public Policy program (International & Global Affairs). I'm building MoyoMap at SenTeGuard: living maps of what AI knows, so research compounds instead of disappearing into chats.
What I work on
I build security products and policy frameworks for the "meaning layer" of AI systems: preventing sensitive knowledge from leaking when employees summarize, paraphrase, translate, or repackage internal information through LLM tools.
My focus is practical: enterprise AI adoption that holds up under real compliance constraints (privacy, export controls, regulated R&D, and national-security environments), without slowing teams to a crawl.
Products
- MoyoMap: living maps of what AI knows, so research compounds instead of disappearing into chats.
- Moyo Scan: a one-off research report when you want a deliverable rather than a workspace.
- SenTeGuard: a locally deployable guardrail, and the legal entity behind MoyoMap and Moyo Scan.
See projects for related work on Joseki and the Idea Security Verification Framework.
