Additional information

Research area

The research of Georgios Kelesidis focuses on characterization and control of flame-made nanoparticle size, morphology and optical properties.


Aerosol processes, such as agglomeration, surface growth and condensation are simulated by Discrete Element Modeling (DEM) to quantify their effect on particle structure and size distribution. This allows the derivation of easy-to-use scaling laws describing the fractal-like morphology of major atmospheric pollutants, such as soot, assisting their monitoring and mitigation. The DEM-derived relationships are validated against experiments to provide a better understanding of particle formation and growth. This understanding facilitates also the design and optimization of functional materials with inudstrial and biomedical applications.


Motivated students are always welcome to do simulations and/or experimental work for their BSc & MSc projects or as research assistants.
