Tess joined the Advanced Lighting Team at PNNL as a Post-Masters Research Associate in 2013. Prior to joining PNNL, Tess was introduced to both the potential and challenge of lighting paintings through her work on conservation sites in Cyprus, Georgia, and the UK and during her thesis work, supervised by Jim Druzik (Senior Scientist, The Getty Conservation Institute). Her dissertation, "An Assessment of LEDs for the Illumination of Wall Paintings", showed that evaluating SSL for wall paintings is not just about matching color temperature and replacing daylight or incandescent lighting with LEDs. Throughout her thesis, issues of subjective values were raised alongside the physical parameters of luminance and color perception which Tess hopes to pursue in future study. Tess is currently focused on the evaluation of emerging SSL technologies and learning about the beauty of light under the guidance of a very talented lighting team.
