Profile

I have taught in the School of Architecture since 2005, having previously taught at UMIST (1993-1998), Robert Gordon University (1999-2000) and Sheffield Hallam (2000-2005).

I supervise research of lighting; how does lighting affect our perception of space and our ability to perform visual tasks. A main application for this work is lighting for pedestrians and cyclists. We also conduct research on research methods, for subjective evaluations such as spatial brightness, discomfort from glare and pedestrian reassurance, and objective evaluations such as the interpretation of eye tracking data. This work, conducted within the Lighting Research Group, has led to new national and international guidance for lighting design.

I established two fora for PhD students of lighting: LumeNet, the research methods workshop, and BrightLights, where new researchers find out about the established researchers.

Qualifications

PhD; UMIST, 1997

Research interests

I am interested in lighting, visual perception and visual performance, for electric lighting and daylighting.

Questions include:

  • Lighting for pedestrians and cyclists: how does lighting affect safe movement and perceived safety?
  • Approaches for establishing appropriate lighting conditions in design guidance.
  • The influence of test procedure on the results of an experiment unintentional experimental bias.

Teaching interests

My teaching discusses heating, ventilation and lighting services using a bottom-up approach, questioning firstly whether there is a need for particular services, and then whether provision be met through design of the building form and format a mixture of conservation and passive approaches. Is it possible for dwellings in the UK to be comfortable in winter without mechanical heating systems?

Of course in many situations mechanical systems are needed, and thus services are discussed to give the architect sufficient ideas for practice: what services are needed, where are the main items located and what size are they, and what questions should I ask the building services consultant?

These ideas are delivered through lectures and tutorials for studio projects. Currently, my teaching centres on two areas:

  • Supervision of PhD students investigating lighting
  • Part I and II: Environmental design - lighting

This is what a former student thought of my teaching:

Of course, any new housing wouldnt be complete without insulation and central heating! This was the first time we have ever done a detailed services task and I think my naivety probably came through as this assignment took far longer than anticipated! However, Steve Fotios a very enthusiastic module leader who remained passionate about every type of radiator, ventilation system and water system had produced detailed notes which were a massive help! It is also worth mentioning that this submission wouldnt have been the same without our very own tutorials from an ARUP engineer!
