Natural Material Innovation

Sustainable Living


Eleni completed a MEng with honours at the National Technical University of Athens in 2010 with specialisation in Concrete and Steel Design and Earthquake Engineering. She holds a Master's degree with distinction in Structural Steel Design and Sustainable Development from the Imperial College. She completed her PhD in the Concrete and Composite Structures group at the Engineering Department University of Cambridge in 2015. The research project was on the Durability and bond performance of Carbon Fibre Reinforced Polymer (CFRP) tendons in high strength concrete in collaboration with the Swiss Federal Laboratories for Materials Science and Technology (EMPA in Zürich). After completing her PhD degree she worked as a Structural Engineer at Foster + Partners in a interdisciplinary design environment. Eleni joined the Natural Material Innovation (NMI) group in 2017 studying the mechanics of timber from micro- to macroscale in close collaboration with biochemists, chemists and fluid mechanical engineers. Her research focus on timber connections (with steel and composite materials) and tall timber buildings. Research interests also include footfall vibration analysis of timber floors and biomechanics.

New insight into the structure of building blocks of plant biomass.

6 November 2018

In a paper recently published in Plant Physiology we investigate the structure and function of one of an important component of plant biomass – galactoglucomannan (GGM). The GGM is a polysaccharide, a polymer made from multiple sugar molecules joined together. It is one of the principal components of softwood, wood from...
