His involvement in Systems Innovation and Entrepreneurship has led to a successful bid to coordinate Innovate EUt of the EIT HEI Initiative call.

Stelios holds a Master of Engineering in Civil and Environmental Engineering from Imperial College London (UK) and a PhD in nonlinear structural mechanics from the same university.

He is a Member of the Cyprus Scientific and Technical Chamber (ETEK), Graduate Member of the Institution of Structural Engineers (IStructE), Associate Member of the American Association of Civil Engineers (ASCE), Chair of the Stability Committee of the ASCE Engineering Mechanics Institute, Member of the Leadership Council of the UN Sustainable Development Solutions Network in Cyprus and National Representative at the CEN/TC350/SC1 for circular economy in the construction sector.

In 2008, Stelios and his collaborators received the Trevithick Prize for the Best Paper in Engineering Sustainability from the Institution of Civil Engineers. In 2015 he was awarded merit in Excellence in Structural Engineering Education by the Institution of Structural Engineers for his innovative teaching case study for Integrated Design.

His research interests include nonlinear structural mechanics, novel multifunctional structural materials, entrepreneurship and sustainability in construction and design, systems innovation, biomimetic design and innovation in Engineering Education.
