Research
Which sensors deserve to be believed.
Most of my research is about integrity: deciding, in real time, how much an autonomous system should trust each of its own inputs. Each entry states exactly how far its evidence goes.

Systems paperMeasured Self-Occlusion in a Deployed Cross-Sensor Diagnostic LayerMeasurements of false-healthy exposure in a deployed diagnostic layer for small uncrewed aircraft, that is, how long it reports a sensor as healthy without the evidence to back that up.Submission package, October 2026Read 
Mathematical paperPosterior Distortion from Hypothesis-Dependent Validity Gating in Runtime DiagnosisWhen a runtime monitor uses a validity gate only to pick which evidence to score, it throws away a diagnostic observation. This paper gives an exact account of what is discarded and when it changes the answer.Preprint v2.2, September 2026Read
