Dr. Leonidas-Sotirios Kyrgiakos

PhD of the Laboratory of Agricultural Economics and Consumer Behaviour · former postdoctoral researcher
Research Field: Optimisation, Agricultural Economics
Expertise: Data Envelopment Analysis (DEA)

Leonidas-Sotirios Kyrgiakos completed his doctoral research at the Laboratory of Agricultural Economics and Consumer Behaviour of the University of Thessaly and went on to work at the Lab as a postdoctoral researcher. His doctoral work assessed the sustainability of different agricultural sectors in the context of climate change, seeking to optimise input-use efficiency and mitigate environmental impacts.

Methodologically he specialises in Data Envelopment Analysis (DEA), combining operational, energy and environmental dimensions, and in the visualisation and dissemination of results with tools such as R and Tableau. During his time at the Lab he contributed to the CropFeed, ALLIANCE and NATAE projects, among others.
