Invited Speakers


Françoise Viénot, FR


Professor Françoise Viénot (born 1946) is Emeritus Professor at the Muséum National d'Histoire Naturelle, in Paris, France. As a physicist, she has been trained by Yves Le Grand.. She has also spent a few months at Professor Billmeyer's Laboratory at Rensselaer Polytechnic Institute, Troy, New York. Her expertise is in the field of colour vision and the measurement of appearance. She has been conducting research and supervising graduate and postgraduate students at the Muséum National d'Histoire Naturelle in colorimetry, the relationship between colorimetry and physiology, mesopic photometry, fundamental colorimetry and its application to colour-blindness simulation (in collaboration with John Mollon from Cambridge University), LED illumination, BRDF analysis and gloss measurement. Recently, her interest has been directed to the application of metameric blacks to investigate the response of melanopsin retinal ganglion cells. Her present field of application concerns Museum artefacts conservation. She has been responsible for applied research projects on visual metrics. She has been teaching Color Vision and Colorimetry at Paris-Sud University and Poitiers University (ESIP). She is co-author of Vision et Mesure de la Couleur by Kowaliski, Viénot and Sève, and coordinator with Roque and Bodo of Michel-Eugène Chevreul. Un savant, des couleurs! She is Past President of CIE-France, chair of CIE TC 1-36 on the "Chromaticity diagram with physiologically significant axes" and has served as Associated Director for Vision for Division 1 of the CIE. She serves on the editorial board of Color Research and Application. She received the Prix Alfred Monnier from Association Française de l’Eclairage (1997), was presented the David Palmer Lecture from the Colour Group of Great Britain (2006) and has been awarded the Newton medal from the Colour Group of Great Britain (2012), the Verriest Medal from the International Colour Vision Society (2013), the Judd award from the Association Internationale de la Couleur (2015).

Tessa Pocock, US


Dr. Tessa Pocock started out her career in plants with a diploma in Horticulture at Olds College, Canada after which she worked in research and commercial greenhouses. Her interest in plant responses grew and she pursued an Honors BSc in plant science, am MSc in plant biochemistry and a PhD in plant physiology at the University of Western Ontario, Canada. Dr. Pocock was a recipient of a prestigious Marie Curie Fellowship that took her to Sweden to study the effect of climate change on aquatic organisms. After her post-doctoral fellowship she was offered a position as Director of Research for a small horticultural LED manufacturer in Sweden. During her time in industry, Dr. Pocock and her collaborators at Chalmers University of Technology, received 2.6 M USD in funding from the Swedish Foundation for Strategic Environmental Research to develop a biosensing and control system that resulted in two European patents and one Swedish patent dealing with light optimization and recovery of plants from stress using multichannel, controllable LED fixtures and sensors. Coming back closer to home, she has recently started work at the Smart Lighting Engineering Research Center at Rensselaer Polytechnic Institute (RPI) where she has started up a multi-disciplinary light and plant research program.


Takashi Usuda, JP

  Dr. Takashi Usuda is the Director of Research Planning Department and the Deputy Director of the National Metrology Institute of Japan (NMIJ).
He started his career in optical device testing in industry in late 80s. After he joined national metrology institute in 1990, he transplanted the metrological approach to transducer evaluation including optical devices. He also applied optics in acoustics and vibration measurement. His current interest in metrology is dynamic quantities measurement (vibration, time dependent deformation, etc.) by laser interferometry. He spent a guest researcher position in Physikalisch-Technische Bundesanstalt (PTB 1998-1999, Germany), in Centre national de la recherche scientifique (CNRS 2000-2001, France), and in Bureau International des Poids et Mesures (BIPM 2010-2011, France).
He obtained his master and doctor degree from Tokyo Institute of Technology. He has been President of Consultative Committee for Photometry and Radiometry (CCPR) under Metre Convention since 2012.


Arnold Wilkins, GB


Professor Arnold Wilkins obtained his doctorate from Sussex University for work on human semantic memory and then spent two years at the Montreal Neurological Institute (1972-1974) where he became interested in photosensitive epilepsy. He worked at the Medical Research Council Applied Psychology Unit, Cambridge from 1974 until 1997, and he is now a professor at the University of Essex. His investigation of the effects of rapid flicker on eye-movement control led to the discovery that fluorescent lighting can be detrimental to health. He developed a system for ophthalmic tinting that is now used to treat perceptual distortion in neurological disease. He recently contributed to an IEEE committee concerned with flicker from LED lighting.


Geoff Draper, GB

Geoff Draper retired in March 2009 after a career spanning 47 years in vehicle lighting and is now leading GTB where he was chair of several working groups since 1990.
After qualifying as a Mechanical Engineer he worked in optical development and later as Chief Lighting Engineer for Lucas. Subsequently he managed Forward Lighting Development at Magneti Marelli in Italy and  later returned to the UK as Managing Director of Gilardini UK Ltd. In 1998 he accepted an invitation to join Koito Europe as Technical Director based in Belgium and in the last five years before his retirement he directed the Koito regulatory affairs and concentrated on his work in GTB, CIE (as chair of TC4-45) and SAE.
Now, in addition to his duties as GTB President, Geoff is a member of the ISAL and IFAL Steering Boards and a regular contributor to SAE Lighting Committee meetings and the Driving Vision News Workshops.
