Dr. George Efthimiou | Mathematical Engineering | Best Researcher Award

Research scientist | FLUENC | Greece

Dr. George C. Efthimiou is a distinguished researcher specializing in Computational Fluid Dynamics (CFD), environmental modeling, and exposure prediction in urban and industrial environments. He earned his Ph.D. in Mechanical Engineering (2013) from the University of Western Macedonia, Greece, where his doctoral work focused on the Prediction of Individual Exposure using Computational Fluid Dynamics Modelling under the supervision of Professor John G. Bartzis.

His multidisciplinary background, combining energy resource management and mechanical engineering, underpins a career devoted to advancing sustainability, atmospheric dispersion modeling, and risk assessment methodologies.

Dr. Efthimiou has held key research positions at leading Greek institutions, including:

• Postdoctoral Research Fellow at the Nuclear & Radiological Sciences & Technology, Energy & Safety Division, N.C.S.R. DEMOKRITOS (2014–2019)

• Research Associate at the Sustainability Engineering Laboratory (SEL), Aristotle University of Thessaloniki (2019–2024)

• Research Scientist at the Advanced Renewable Technologies & Environmental Materials in Integrated Systems Laboratory, Centre for Research and Technology – Hellas (CERTH)

His scientific contributions span urban air quality modeling, hazardous pollutant dispersion, exposure assessment, and renewable energy systems. His studies have provided validated methodologies for predicting human exposure to airborne hazards and have influenced policy and safety assessments in both industrial and environmental contexts.

Dr. Efthimiou’s research has been featured in international conferences and peer-reviewed journals such as Toxics, Fluids, and the Journal of Hazardous Materials Advances, highlighting his role in bridging theoretical modeling with practical environmental applications.
