DAS for environmental monitoring
ActiveTelecom fiber as a wide-area environmental sensor
Monitoring seismic events, tides, thunderstorms and wind using deployed telecom fiber, toward DAS-based early-warning systems.
Products and instrumentation I build outside the lab, and a few research tools I've open-sourced.
Telecom fiber as a wide-area environmental sensor
Monitoring seismic events, tides, thunderstorms and wind using deployed telecom fiber, toward DAS-based early-warning systems.
DAS arrays for noise cancellation in GW detectors
Using DAS arrays to cancel correlated ground motion in LIGO and the Einstein Telescope, with a focus on sensor placement, Wiener filtering, MVDR and machine-learning methods.
Enhanced low-frequency sensitivity, validated in the field
Building interferometric DAS with improved low-frequency sensitivity, validated against geophones and seismometers in the lab and in the field.
Concrete curing, wind, and coherence analysis
DAS monitoring of concrete curing and wind effects, with environmental coherence analysis using PCA, EOF and semblance methods.
From Kerr-effect mitigation to sensing infrastructure
Earlier work on high-capacity optical communication and nonlinear Kerr-effect mitigation, and energy-efficient elastic optical networks — now feeding into fiber-sensing performance.
