Gareth has a background in physical chemistry, in particular optical spectroscopy of photochemical and fluoresence systems. With a PhD specialising in sensing using photonic crystal fibers from the University of Edinburgh in association with the Max Plank Institute for the Science of Light, he specialises in buiding novel opto-mechancal solutions to complex scientific problems.

After his PhD, Gareth moved onto several diverse areas of optical spectroscopy device development cumulating in the formation of a startup company to deliver his designs from prototypes to delivered products. Within the THT Group, Gareth helps deliver exciting new tools for sensing in the distal lung.
