The paper 鈥�鈥�, is based on research Ben undertook for his MSc for a module on Lighting Research where the students were asked to write about the influence of light on health and wellbeing. Ben was inspired by the topic because of 鈥渢he underlying theme that human evolution hasn鈥檛 kept up with the rapid rate of change we鈥檝e made to our environment. It鈥檚 only in the last 150 or so years that people spent so much time indoors.鈥� This disparity leads to a complex problem; 鈥渨orking out which properties of natural light we need and which parts we can safely leave out when it comes to recreating it artificially.鈥�

The paper provides a summary of the key experimental studies which have driven understanding of this subject forward.

Ben said that initially the research was quite challenging:

鈥�It鈥檚 a subject that鈥檚 seen a lot of research in recent years due to the discovery that there are light sensitive receptors in our eyes that aren鈥檛 entirely used for vision. They鈥檙e used for (among other things) the timing of circadian rhythms, so that our brains know when to sleep and when to be alert. The task was to distil the research that鈥檚 been done so far into a coherent story, which was quite a challenge as it鈥檚 an area that鈥檚 still very active and unresolved.鈥�

Research in this area could have a wide-ranging impact, especially for lighting designers. For instance, 鈥渋t could provide a solid basis for reducing the amount of light we鈥檙e exposed to at night in public areas. It could also affect the design of daytime spaces.鈥�

Ben says that the Light and Lighting MSc was 鈥渁 massively rewarding experience.鈥�

鈥�I think the thing that I would highlight is the range of learning that you engage in over the year. We did everything from hand sketching to programming to physical model making, academic research, factory visits, daylight simulation and practitioner workshops. It鈥檚 a very broad programme which covers a lot of bases, but always in a rigorous and comprehensive way. I think it鈥檚 a result of the many years the programme has been running that the teaching staff are able to fit so much in in a smooth and well organised way, and you do feel in safe hands.鈥�

In the new year Ben will be starting a graduate position at Arup. He said:聽

鈥�ultimately, the course has enabled me to take my career well beyond my initial aspirations.鈥�

We鈥檇 like to thank Ben for taking the time to talk to us and wish him luck in his new job.
