Academic Profile

Yiorgos is an agricultural economist with research interests in the environmental conservation and the sustainable intensification of agricultural production systems. In particular, his work investigates transitions of livestock production systems towards more universal sustainability with a particular focus on the development of global livestock investment models.

Yiorgos holds a BEng and an MEng in Spatial Planning and Development Engineering from Aristotle’s University of Thessaloniki and a PhD in Agricultural and Food Economics from the University of Reading. Incorporating geo-spatial and financial modelling techniques, his doctoral thesis studied the sustainable development of agricultural systems and the environmental conservation within the Less Favoured Areas of England. In a theoretical context, it constructed a policy framework to enable the sustainable intensification and diversification of upland livestock production systems.

Current Research

Yiorgos is currently involved in the Wellcome Trust funded Livestock Environment and People (LEAP) project. His current research focuses on livestock transitions identifying productivity gains through switches to more productive systems, including changes from-grass based to mixed systems. Through this work he develops a novel global livestock costing and investment model to enable agricultural intensification addressing socio-economic and biophysical functions that drive global cropland and grassland expansion.


Yiorgos has experience in undergraduate teaching from the School of Agricultural Policy and Development, University of Reading in the subject area of agricultural economics and management.

Previous Projects

Sheep Performance Improvement through Lameness Monitoring and Management (SPILaMM) aimed at addressing the challenge of sheep lameness, a predominant cause of both poor productive and reproductive performance causing a reduction in product value to the farmer, processor, retailer and consumer. The project was funded by Innovate UK and involved partners from the industry including Dunbia and Farm Wizard, with the University of Nottingham as academic lead.
