Judith is a Professor at London South Bank University (LSBU). She has 35 years’ experience of working on food refrigeration operations throughout the food cold chain from harvest/slaughter to the consumer. During her career Judith has worked on a number of topics including frozen storage of meat, consumer handling of food and studies to improve the performance of domestic and commercial refrigerators, energy labelling, instrumentation performance, decontamination of food, cook-chill systems, novel refrigeration systems, optimising refrigeration systems and improving performance and temperature control in chilled and frozen storage rooms.

The current focus of her work is on efficiency and carbon/energy reduction as well as design and performance of refrigeration equipment. This covers cold chains in the UK and Europe but also in low-income countries such as Bangladesh, India, Kenya and Rwanda.

Judith has published 153 papers, 5 books and 17 book chapters. Professionally she is a Fellow of the IOR (Institute of Refrigeration), a member IOR national Technical Committee, president of the IIR (International Institute of Refrigeration) C2 commission (food science and engineering), vice presidents of the CaRe (careers in refrigeration) working party and the cold chain in warmer climates working party and a member of the D1 (retail display cabinets) committee. She is also the UK, IOR representative to the IIR and also an editor of the Journal of Refrigeration.
