Professor John Crawford

Computational Systems Science Dude (School of Geographical & Earth Sciences)

Biography

John Crawford is Professor in Strategy and Technology Management and a theoretical biologist with a research focus on systems approaches. He has active programmes of research on the integrated behaviour of the soil-plant-microbe system, food system optimisation; and in the application of AI in systems biology including tissue- and organ-level modelling of Alzheimer’s Disease.

Professor Crawford was previously Science Director at Rothamsted Research in the UK and Complex Systems programme lead in the executive team for the University of Sydney’s $0.5B Charles Perkins Centre, linking sustainable agriculture, food, diet and health. He was the Academic Champion for the UKRI’s successful bid to the UK Government for the £90M Industry Strategy Challenge “Transforming Food Production” programme and remains on the Steering Board. He is also current Chair of BBSRC’s Committee B.

In addition to academic work, Professor Crawford has undertaken consultancies with major multinational companies at the strategic level including supporting one of the largest acquisitions and mergers in history.
