Office Hours: By appointment

I graduated in 2009 from the Department of Mechanical Engineering at the University of Thessaly, before joining the CSE Lab at ETH Zurich as a research assistant. I joined the University of Strathclyde in 2011 as a PhD student in the James Weir Fluids Laboratory under the supervision of Prof. J. Reese. In 2014, after defending my PhD thesis on Nano and Micro-Scale Fluid Dynamics, I got a new role in the University as a Research Associate. In this role I was the Fluid Dynamics Expert of the Weir Advanced Research Centre working on a range of projects involving centrifugal pumps and safety relief valves. In 2015 I got the position of Lecturer in Multi-Physics Fluid Mechanics at the Department of Mechanical and Aerospace Engineering.

My research involves Multi-physics modelling of advanced fluid mechanics applications using a range of programming languages (Fortran 90/95, C/C++, Python, Perl, Matlab) as well as commercial CFD tools such as OpenFOAM, Fluent and Star- CCM+. My research interests cover a broad area including the study of supersonic and hypersonic transitional and turbulent flows. The acoustic loading on aerospace structures. Modeling of flows within centrifugal pumps, with a specific focus on the development and assessment of computational tools to improve the design of pumps and valves for use with slurry based fluid mixtures. Multi-phase and multi-scale study of immersion quenching and heat transfer with phase change across the length scales, from nano to macro. Development and use of various computational tools involving Molecular Dynamics, Coarse Grained Molecular Dynamics, conventional CFD and Machine Learning techniques to minimise empiricism in the field. And finally, modelling of fluid flows inside and around micro and nano structures
