Prof. Walter Johnstone serves as Research Professor of Photonic Systems within the Department of Electronic and Electrical Engineering at the University of Strathclyde's Faculty of Engineering. Previously holding leadership roles including Head of Electronic and Electrical Engineering (2006-2011) and Vice Dean (Research) for the Faculty of Engineering (2011-2016), he currently focuses exclusively on research leadership and implementation while maintaining active industry collaborations.
His research centers on laser spectroscopy applications for accurate gas concentration, pressure, and temperature measurements in extreme environments such as combustion zones and exhaust plumes of gas turbine engines operating at temperatures up to 1000°C. The Photonic Systems research team develops commercially deployable sensing systems through close partnerships with Rolls-Royce, Shell, OptoSci Ltd., and M Squared Lasers. Recent work integrates machine learning with laser absorption spectroscopy for combustion diagnostics in harsh environments.
Key research contributions include:
- Development of tunable diode laser spectroscopy for high-temperature gas measurements
- Miniaturized photoacoustic gas sensing systems
- Commercialization of spectroscopic gas measurement technologies through OptoSci Ltd.
His work contributes to UN Sustainable Development Goals through advancements in clean energy technologies. Notable recognition includes the 2022 Applied Optics Best Paper Prize for Imaging Systems.
Professor Johnstone maintains active research funding through projects like LITECS (Laser Imaging of Turbine Engine Combustion Species) and EPSRC Industrial CASE accounts, with significant editorial contributions as former board member of the Journal of Measurement Science and Instrumentation.
