His Ph.D. research involved the development and testing of an IR intrapulse QCL spectrometer and its application to trace gas detection and nonlinear optics. This involved improving its control and data acquisition systems coupled with the design of analysis software to process the results obtained from a wide selection of field measurements.

Abstract

We present here an open-path analyser, initially intended for security applications, specifically for the detection of gas plumes from illicit improvised explosive device (IED) manufacturing. Subsequently, the analysers were adapted for methane measurement and used to investigate its applicability for leak detection in different scenarios (e.g. unconventional gas extraction sites). Preliminary results showed consistent measurements of gas plumes in the open path.
