About
I received my Ph.D in mathematics studying algebraic geometry and string theory. I now work in the public sector developing secure, constrained environments for agentic workflows in both the cloud and at the edge.

- How Geometric Torsion at Sub-Planck Lengths Prevents the Existence of Special Classes of Residual D-BranesMay 1, 2026A walk from a polynomial drawing a circle to the proof that the Kuznetsov component of a generic Enriques surface admits no Serre-invariant Bridgeland stability condition. The obstruction is concrete: one phase computation says +2, another says +3, and the category cannot tolerate both.
- Supersingular Isogeny Diffie-Hellman: A Beautiful Idea That Almost WorkedApril 29, 2026SIDH was the most mathematically elegant post-quantum key exchange candidate — compact keys, deep algebraic structure, and a compelling diversity argument — until a 1997 genus-2 paper destroyed it in under an hour on decade-old hardware.
