Some of us met for the first time at a workshop in 2019, while some already knew each other from before. We have never met as a group, but we are united by a strong interest in the permanent possibility of exchanging knowledge and working together.

Myriam Aries

PhD in Lighting Technology

School of Engineering, Jönköping University

Expertise: Human Factors in Lighting, Lighting Science, Lighting Technology

Myriam.Aries@ju.se

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.besenecker@arch.kth.se

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.hemphala@design.lth.se

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.linden@design.lth.se

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, Radiation Sciences & Molecular Biology

WCMM, Umeå University

Expertise: Behavioural Biology, Chronobiology, Sleep, Mental Health, Light Therapy.

Katharina.wulff@umu.se

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.
