I map failure patterns across complex systems and build the security boundaries required to stabilize them.
I'm the founder of Project Navi - an open-source AI security company focused on zero trust architecture and mathematical governance. Before that, I spent seven years in behavioral health research, coordinating peer-support programs across 500+ organizations and publishing on workforce collapse in the APA Psychiatric Rehabilitation Journal.
The same structural breakdowns I studied in human systems - drift under pressure, coherence loss at scale, collapse when governance is bolted on instead of built in - show up in AI deployments. So I started building infrastructure to prevent them.
Takens' theorem for generic pairs, machine-checked. On a compact smooth d-manifold, the pairs (T, h) of a C² diffeomorphism and a C² observation whose delay map with 2d+1 coordinates is a C² embedding are open and dense in Diff²(M) × C²(M, ℝ). Also finite-regularity Sard (via a port of Moreira's theorem), exact finite-state horizons and ordinal codes. Lean 4 + Mathlib v4.34.1; no sorry, standard axioms only.
Box-counting dimension of the (u,v)-flowers, machine-checked. For 1 < u ≤ v, the Rozenfeld–Havlin–ben-Avraham flowers have dimension log(u+v)/log u: as the limit of their recurrences, as a log-ratio of the explicit graphs, and as a box-counting dimension over minimum box covers at every resolving scale. Lean 4 + Mathlib v4.34.1; no sorry, standard axioms only.
Existence theory for the Creative Determinant boundary value problem −ΔΦ = a|∇Φ| + bΦ − c(Φ₊)ᵖ. On finite weighted graphs, a positive solution is fully proved; the continuum results are conditional on explicit, documented elliptic hypotheses. Lean 4 + Mathlib v4.34.1; standard axioms only. Theory in the paper.
Deterministic input sanitization for untrusted text in LLM pipelines. Strips homoglyphs, invisible Unicode, null bytes, template injection, and path traversal vectors. Zero dependencies. Python 3.12+. Live on PyPI.
Agent Skills for coding agents: start and release Python packages, add or repair CI, harden the supply chain, keep docs accurate, review changes and verify findings, and calibrate measurements or refuse bad fits. Each skill is a standalone folder of instructions with checked examples, exercised by agents on throwaway projects.
