SESSION 1: VISION

Gilles Vissenberg (born 1972, St. Maarten, Dutch West Indies) is principal scientist lighting applications at Signify Research, Eindhoven, The Netherlands. His current and previous work interests are optical design of LED lamps and luminaires, lighting application research, office lighting, energy saving and quality of light. He worked on LED spot lights and general illumination LED lighting systems, with a focus on low-glare solutions. He Dutch voting member of CIE division 3 (interior environment and lighting design) and was involved in the recent correction to the unified glare rating (CIE 232: 2019). He holds a Ph.D. from Leiden University, the Netherlands, and a Master degree in Theoretical Physics from the University of Nijmegen, the Netherlands. He published over 30 scientific papers and filed over 170 independent patent applications (88 patents are granted in the USA), mainly on illumination optics and LED lighting applications.

Małgorzata Perz was born in Poland in 1984. She goes by Gosia. She completed her secondary education at the Sports Championship High School in Szklarska Poręba, where she practiced biathlon. She studied Information and Communication Management at Neisse University and received her BS diploma in 2006. She continued her education at Wrocław University of Technology and in 2007 she earned Inzynier (Ir) degree in Computer Science and Management. Meanwhile, from 2006 to the end of 2007 she worked at Capgemini (PL), holding position of an Incident, Problem & Change Manager. In 2008, she moved to The Netherlands where she enrolled at Eindhoven University of Technology and followed Human-Technology Interaction program. In 2010 she received her MSc degree, following her diploma internship at Philips Research Europe. After graduation she worked at Philips Research and since 2016 she works at Signify Research, holding position of Scientist Optics Light & Vision. In her work she mainly focuses on studying different aspects of quality of light, including temporal, e.g. flicker, and the stroboscopic effect, spatial, e.g. glare and sparkle, and spectral, e.g. whiteness. From 2014 to 2019 she conducted research at TU/e Intelligent Lighting Institute, resulting in a thesis entitled Modelling Visibility of Temporal Light Artefacts for which she was awarded her PhD cum laude.

Arnold Wilkins is a Fellow of the British Psychological Society and an Honorary Fellow of the College of Optometrists. His postdoctoral study was undertaken at the Montreal Neurological Institute where he became interested in photosensitive epilepsy. He then spent 22 years at the Medical Research Council Applied Psychology Unit in Cambridge studying light sensitivity as it occurs not only in epilepsy, but migraine and dyslexia.  In 1997 he moved to a chair at the University of Essex, where he is now Emeritus. He has published extensively on visual stress and authored three books.

Jim Uttley has a background in Psychology and Behavioural Science. His research applies principles of behavioural research and environmental psychology to the built environment. One of his main interests is the influence of the built environment, particularly lighting, on active travel.
