She is also actively involved with her professional association, the International Association of Lighting Designers, and was elected to the main board and IALD Education Trust from 2005 – 2008; highlights of this service included chairmanship and re-branding of the IALD Annual conference, Enlighten, in 2006.


In 2000, she became fascinated with the effect of light on the body and undertook to collate the research of the time into an accredited RIBA CPD lecture, designed to explain current advice and suggest lighting approaches and techniques for projects. Mary and her team designed the lit environment at Pines Calyx, completed in 2008; the final scheme is one of the first bio-dynamic lighting schemes using coloured light in the UK.


She continues to research collaborating with CIBSE and Dr. Meher Engineer since 2014 to demonstrate the effects of light and colour. The events aimed to raise awareness of the physiological and psychological effects of light and colour, both as ambient light and for ‘personal use’. They included an opportunity to experience the coloured light therapy of the Monocrom system. designed by architect and psychologist Karl Ryberg. Her experience of lighting design includes both daylight analysis and artificial light for a range of commercial spaces, artworks and residential schemes, both at home and abroad.
