I am a  theoretical plasma physicist and a  member of the Plasma Physics group since 2009 when I was awarded a full  EPSRC  scholarship to study Plasma Physics, resulting to my PhD degree. I  had previously obtained my BSc degree (Honours) in Physics from the Aristotle University of Thessaloniki, Greece and  my MSc degree in Quantum Fields and Fundamental Forces from Imperial College London in the field of Theoretical Physics with focus on early universe cosmology.

Research Interests

My research is focused on the basic physics of dust-plasma interactions, plasma-surface interaction in the area of  Magnetic Confinement Fusion (MCF). During my PhD I studied plasma sheath related phenomena and its application on the charging  of large dust grains. My PhD research  included both analytical and computational work, and for the latter I also developed, in collaboration with the Rutherford Appleton Laboratory (RAL), the kinetic Vlasov code Yggdrasil-PSI to study plasma-surface interaction phenomena.

My current interests include: dust-plasma and plasma surface interactions, sheath physics, tokamak physics, dust transport and kinetic plasma simulations. I am currently interested in expanding my research in the other areas such as the fields of early universe cosmology and astrophysics.

I am also an Imperial College Outreach Ambassador and Leader and I have a strong interest in promoting STEM subjects and fusion research. I have given a number of talks to students of all levels and their teachers. The most recent examples (November 2017) include my talk at the Physics department  to 275 students (Year 9) and their teachers, and also my talk at the Creative Quarter event where leading cultural and educational organisations in South Kensington like the Science Museum and Imperial College take part.
