Light has a profound impact on us, by enabling us to see and synchronizing our circadian physiology to the external light-dark cycle. To understand the exact effects of light in the real world, however, requires ways to measure or estimate light dose. This multi-speaker webinar will explore cutting-edge research on measuring light exposure in a personalized fashion in the field.

The webinar will consist of four research-based talks from an international team of speakers working on advancing ways that light exposure can be measured in people:

"Measuring geographical and seasonal variation in colour and light exposure​" presented by John Maule

"The Light-Dosimeter – a novel, portable device to record an individual’s light exposure" presented by Janine Stampfli & Bjoern Schrader

"Spectrace: a compressive spectrometer for personal light tracking" presented by Forrest Webler

"Towards a global database of daily corneal light exposure using wearable spectral sensors" presented by Vineetha Kalavally

What You Will Learn:

  • Recent research on wearable light measurement devices and light dosimeters
  • How light exposures change in different contexts, including seasons and geographical locations
  • Technology to track light exposure

Who Should Attend:

  • Anyone interested in the measuring light using wearable devices
  • Anyone interested in the impact of light on visual and non-visual physiology

About the Presenters:

John Maule, Sussex University

Dr. John Maule is a senior research fellow in the Sussex Colour Group. His research covers a range of topics in colour vision and perception including visual averaging and ensemble statistics of colour, colour perception in autism, and adaptation. His current work seeks to quantify the chromatic statistics of different environments and measure their effect on colour perception and aesthetics.


Janine Stampfli, Lucerne University of Applied Sciences and Arts

After studying business and economics at the University of Basel (Switzerland), Janine Stampfli went abroad in 2004 and worked as a project manager for an NGO and later for a private sector company. She got a MSc in Light and Lighting from University College London (United Kingdom) in 2017 and has been part of an interdisciplinary research team focused on light and lighting at the Lucerne School of Engineering and Architecture (Switzerland) since 2018.


Björn Schrader, Lucerne University of Applied Sciences and Arts

Björn Schrader studied at the Technical University of Braunschweig (Germany) and at the Technical University of Ilmenau (Germany), specialising in media technology/lighting technology. After graduating, he worked as a lighting designer at Zumtobel AG and later as a senior lighting consultant at Amstein & Walthert – both in Zurich (Switzerland). He has been a full-time lecturer at the Lucerne School of Engineering and Architecture (Switzerland) since 2011 and heads the interdisciplinary research team Licht@hslu.


Forrest Webler, EPFL

Forrest Webler is a PhD student at the laboratory of integrated performance in design (LIPID). His work relates to spectral sensing and will be discussing his work towards the development of a wearable sensor for spectral monitoring.


Vineetha Kalavally, Monash University

Dr. Vineetha is currently leading a research group focused on Solid State Lighting (SSL) at Monash University Malaysia. She applies light and color science fundamentals to Intelligent control of SSL systems with an industry focus and the goal of realizing energy-efficient human-centric lighting systems.
