Post-Doctoral Research Fellows
Dr Lewis Fleming
Lewis obtained his PhD in optical thin films from the University of the West of Scotland in 2018 focussed on optical filtering in optical gas sensors. Since then, Lewis has worked in Post-Doctoral Research (IUK, STFC) and Knowledge Transfer Partnership (IUK) Associate positions. Lewis' main areas of expertise include the design, manufacture and build of; optical systems, thin film coatings (optical, mechanical, optomechanical, semiconductor and functional) and vacuum deposition systems. Lewis holds certifications in Zemax and Solidworks and became a chartered engineer (CEng) through the Institute of Physics in February 2024.
Domantas Laurus-Southgate
Dom obtained his PhD in Chemistry from Heriot-Watt University in 2025, where he also completed his MChem. His work focused on the surface chemistry of cold plasma being applied to plastic waste using air, N2, O2, CO2, and H2 plasmas with HDPE, PP, PET, PS, PVC, and PTFE, in the context of the feasibility of using plasma as a recycling method. He has also completed work in the FELIX facility (Netherlands) on the IR-induced desorption of CO and N2 from interstellar mixed ice systems to contextualise how molecules in various regions of interstellar space may be formed and released.
