Committee Members
We are united by a strong interest in the permanent possibility of exchanging knowledge and working together and that is why we established the Light Collaboration Network. Some of us met for the first time at a workshop in 2019, but it wasn’t until March 2022 that we were able to meet as a group for the first time.
Myriam Aries
PhD in Lighting Technology
School of Engineering, Jönköping University
Expertise: Human Factors in Lighting, Lighting Science, Lighting Technology
Myriam’s research and teaching includes the understanding and impact of dynamic, smart light products and environments on human work and sleep performance as well as the spill-over effects from one architectural environment to another. The group’s research covers lighting solutions in real-time indoor and outdoor settings as well as computational/virtual environments.
Ute Besenecker
PhD in Architecture
KTH Royal Institute of Technology, School of Architecture
Expertise: Architectural Lighting, Exterior Lighting, Lighting Design, Perception Research
Ute has over 20 years of experience combining architectural and lighting design with research related to the impact of light distribution and spectrum on colour and brightness perception in spatial environments, with the objective to support advancements in both lighting technology and architectural design practice. She teaches courses at Master and PhD level, and her current research includes architecture-integrated lighting solutions in a real school testbed, and pedestrian lighting in urban green areas.
Hillevi Hemphälä
PhD in Visual Ergonomics
Lunds Tekniska Högskola, Lund University
Expertise: VERAM, Light. Flicker, Perception, Glare
Hillevi’s work concerns visual ergonomic aspects of work places, such as risks assessments and the connection between eyestrain and musculoskeletal strain as a result of glare, contrast imbalance, flicker or head/body posture. She recently validated the Visual Ergonomic Risk Assessment Method (VERAM) and is now training occupational health care staff in this method. She is working on lighting for hospitals, including rooms for open surgery, minimally invasive surgery, neonatal intensive care, and currently involved in installing human centric lighting for psychiatric wards.
Johannes Lindén
PhD in Physics
Division Ergonomics & Aerosol Technology, Lund University
Expertise: Photometry, Flicker, Temporal light modulation/artefacts, Radiation Safety
Johannes’ research focuses on light measurement, mainly on colour and flicker from light sources. Flicker, or temporal light modulation (TLM), has reappeared as a problem with the advent of LED technology. This requires development of new measures and standards. Johannes has experience in setting-up light measurement laboratories and in teaching photometry and colorimetry.
Katharina Wulff
PhD in Biology
Departments of Radiation Sciences and Molecular Biology, Wallenberg Centre for Molecular Medicine (WCMM), Umeå University
Expertise: Behavioural Biology, Chronobiology, Sleep, Mental Health, Light Therapy
Katharina has worked on the physiological analysis of human biological time-keeping, sleep and mental health for 20 years. Key achievements are the introduction of chronobiological assays into psychiatry and characterising links between circadian/sleep disruption and mental health. She established the ‘Nordic Daylight Research Programme’ (www.katlab.org) at high latitude to study the brain’s sensitivity to the changing speed of daylight unbiased by electrical light, the impact it has on our physiology and how well our mental health rebounds.
Stuart Wales
Events and Communications
Stuart works with arranging our events and communications. Originally from the UK, Stuart now lives in Umeå, Sweden, where he is experiencing first hand the effects of daylight seasonality.
