After her PhD, Evans spent a year at the University of Aveiro. She was subsequently awarded a Marie Curie Fellowship at the University of Paris where she worked as a postdoc on fluorescence of soft materials. Evans left Paris to join the University of Coimbra as a Fundação para a Ciência e Tecnologiapostdoctoral 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. She delivered the 2011 Royal Society of Chemistry Schools lecture on the Chemistry of Light. In 2013 she published the textbook Applied Photochemistry with Springer Publishing. They explored self-assembly of conjugated polyelectrolyte–polyoxometalate networks, with dimensions controlled by the polymer chain length and steric charge distribution. The self-assembly of these lumophores can be used to tune the optical and electronic properties. To understand the morphology of these films and inform the design of performance nanostructured devices, her group use small-angle scattering, spectroscopy and microscopy. Small-angle scattering allows her to study the microstructure of hybrid materials at the near atomic scale. Their conjugated polyelectrolyte work was featured in the ChemComm Emerging Investigators issue. She also worked on oxygen sensitive printable ink sensors. Evans has explored polymer-hybrid materials for luminescent solar concentrators. By controlling the placement and orientation of the lumophore, she showed that it is possible to limit light lost by reabsorption. 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. Her work was featured in the Journal of Materials Chemistry C Emerging Investigators Issue in 2016. She also develops encapsulation techniques to improve device lifetime. She was made an associate professor in 2016. She collaborated extensively with the University of Montpellier as part of a French-Irish collaboration. Evans was appointed a lecturer at the University of Cambridge in 2017 and a fellow of Jesus College, Cambridge. Her group explore soft materials that are responsive to stimuli, nanostructured inks and hybrid nanoparticles. The soft materials respond to light, using photoresponsive surfactants that include an azobenzene group. She was appointed chair of the Royal Society of Chemistry Photophysics and Photochemistry Group in 2017. She founded Senoptica Technologies in 2018 and is the chief scientific officer working on optical sensors developed in Evans' lab. Senoptica Technologies detect defective modified atmosphere packaging, changing colour to alert the consumer to the amount of oxygen in the pack.
