Jim is a psychologist. His PhD (Sheffield University, 2016) used eye tracking to find out where pedestrians look when walking in a natural environment and then used an experiment to identify optimal lighting for a task (obstacle detection) suggested by the eye tracking to be important. He is interested in making sure statistical analyses are carried out properly.

Jim leads work on data analyses for promoting active travel.

Chloe is a psychologist. She is due to submit her PhD thesis in 2019 (Nottingham University). This has used eye tracking to investigate gaze behaviour of drivers as they approach junctions and has investigated the causes of road traffic collisions.

Chloe is researcher on the HAROLD project.

Steve was an engineer. His PhD (UMIST, 1997) was an investigation of spatial brightness at photopic levels. He proposed a brightness model that included the short-wavelength cones and twenty years later finally completed a satisfactory literature review of spatial brightness. He is somewhat cynical about data gathered using rating scales and spurious myths in lighting.

Steve leads the group, with responsibility for the overall strategy, publications, external funding and achieving impact.

Chris originally studied physics. Later on he completed a PhD (Sheffield University, 2007) looking at how the spectrum of street lighting affects brightness and visual performance for pedestrians. This work is reported in several papers.

Chris designs and builds the apparatus we use in experimental research.
