Early life and education

Evans grew up in South Wales.[3] She studied at Swansea University, earning a Master of Chemistry (MChem) degree in 2002.[4][5] During her Masters, she completed an International Association for the Exchange of Students for Technical Experience (IASTE) fellowship at Lonza Group.[3] She returned to Swansea University for her PhD, investigating on light-emitting materials for display technologies.[6][4]

Research and career

After her PhD, Evans spent a year at the University of Aveiro.[4] She was subsequently awarded a Marie Curie Fellowship at the University of Paris[4] where she worked as a postdoc on fluorescence of soft materials.[4] Evans left Paris to join the University of Coimbra as a Fundação para a Ciência e Tecnologia postdoctoral fellow. She moved to Trinity College Dublin in 2009, where she was a lecturer in Physical Chemistry. Her research was funded by Science Foundation Ireland and Enterprise Ireland.[7] She delivered the 2011 Royal Society of Chemistry Schools lecture on the Chemistry of Light.[8] In 2013 she published the textbook Applied Photochemistry with Springer Publishing.[9] They explored self-assembly of conjugated polyelectrolyte–polyoxometalate networks, with dimensions controlled by the polymer chain length and steric charge distribution.[10][11] The self-assembly of these lumophores can be used to tune the optical and electronic properties.[12] To understand the morphology of these films and inform the design of performance nanostructured devices, her group use small-angle scattering, spectroscopy and microscopy.[13][14] Small-angle scattering allows her to study the microstructure of hybrid materials at the near atomic scale.[15] Their conjugated polyelectrolyte work was featured in the ChemComm Emerging Investigators issue.[16] She also worked on oxygen sensitive printable ink sensors.[17]

Evans has explored polymer-hybrid materials for luminescent solar concentrators.[18] By controlling the placement and orientation of the lumophore, she showed that it is possible to limit light lost by reabsorption.[19][20] She minimises waveguiding losses by designing materials with high refractive indices. She demonstrated that perylene carboxdiimide-bridged triethoxysilane can be covalently grafted to siloxane hybrids.[18] Her work was featured in the Journal of Materials Chemistry C Emerging Investigators Issue in 2016.[21] She also develops encapsulation techniques to improve device lifetime.[22] She was made an associate professor in 2016. She collaborated extensively with the University of Montpellier as part of a French-Irish collaboration.[23]

Evans was appointed a lecturer at the University of Cambridge in 2017[3] and a fellow of Jesus College, Cambridge.[4] Her group explore soft materials that are responsive to stimuli, nanostructured inks and hybrid nanoparticles.[24] The soft materials respond to light, using photoresponsive surfactants that include an azobenzene group.[25] She was appointed chair of the Royal Society of Chemistry Photophysics and Photochemistry Group in 2017.[26]

She founded Senoptica Technologies[27] in 2018 and is the chief scientific officer (CSO) working on optical sensors developed in Evans' lab.[28] Senoptica Technologies detect defective modified atmosphere packaging, changing colour to alert the consumer to the amount of oxygen in the pack.[29]
