Professor Anthony Ryan OBE


Tony leads the University of Sheffield’s programme in sustainability research, across pure and applied sciences, engineering and social sciences. His focus is on the global food, water and energy nexus challenge, harnessing the power of the sun for food production and renewable energy.  His research covers sustainable synthesis, structure, processing, and applications of polymers using advanced analytical and measurement techniques. For example, renewable sources for polymer synthesis, organic photovoltaics, maximising the properties of polymers and biopolymers through flow-induced crystallisation, formulation of home and personal care products and polymer foams for high intensity urban agriculture. The emphasis throughout is on understanding the fundamental science & technology in order to minimise resource use.  Tony holds BSc and a PhD from the University of Manchester and a DSc from UMIST.  In 1997 he moved to Sheffield and served as Head of Chemistry before becoming the Pro Vice Chancellor for the Faculty of Science from 2008 to 2016. Tony has also delivered the Royal Institution Christmas Lectures and has an OBE for services to science.

Talk abstract: Making Complex Fluids Work for Refugees

Our research on hydroponics is focussed on the production of high-value crops close to market (urban farming) with a low carbon and water footprint using polyurethane foam as a synthetic soil. I will show how a design of experiments approach can predict the productivity of crops from the reagents used in polyurethane synthesis through the properties of the foam.  

We connected our work on synthetic soils with a waste disposal problem posed by UNHCR - the UN's refugee agency.  They saw dirty unused mattresses, we saw an alternative growth substrate and more than that ‘a problem’ that could actually help. In doing so we developed small-scale hydroponics with refugee communities for use at the household and community scale.
