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.

Jean Pierre Musabyimana is Research Lead at Africa’s Centre of Excellence for Sustainable Cooling and Cold Chain (ACES), where he heads a One Health program that synchronizes immunization systems, seed systems and farming resilience, nutritional security and food safety, and health systems resilience—recognizing that human, animal, plant and environmental health are inextricably linked.

In this capacity, he actively contributes to conceiving and implementing innovative cold chain models for vaccines, diagnostics and antibody development that span sectors and geographies, applying renewable energy refrigeration, IoT-enabled temperature monitoring, and robust biobanking to safeguard biologicals and bolster supply chain integrity in low-resource settings.

An infection biologist with a PhD in Cell and Applied Infection Biology and dual MScs in Biotechnology & Bioinformatics and Global Health Delivery, Jean Pierre leverages his expertise in structural/comparative genomics, vaccine and therapeutic R&D, and advanced bioinformatics pipelines to align laboratory innovation with field needs.

He forges multisectoral partnerships with universities, industry, and government to pilot context-adapted interventions, drawing on One Health insights into urban agriculture, food systems, and resilience and addressing food safety risks through integrated approaches.

Regionally, he co-leads pandemic surveillance, genomics and climate modelling consortia, most notably the EDCTP3-funded GREAT LIFE initiative, which deploys field-portable genomics and novel diagnostics across the African Great Lakes, advancing early detection and response. As Co-PI of the KIVU JUA consortium, he spearheads Mpox epidemiology and immunology research in Central Africa, contributing to the WHO Mpox Genomic Surveillance Community of Practice and serving on Africa CDC’s RISLNET committee. He also co-leads malaria drug resistance surveillance in East Africa, integrating NGS workflows into routine monitoring for artemisinin resistance.

Passionate about sustainable cooling, Jean Pierre weaves environmental engineering, data analytics, and One Health principles to reinforce vaccine delivery, food safety, and overall health system resilience, positioning ACES and Rwanda as models for cross-sectoral, climate-smart public health preparedness.
