Andrea's Home Page

I am Andrea Meo, currently a PostDoc researcher at Mahasarakham University in Thailand in the Magnetic Information Storage Technology Group led by Dr. Phanwadee Chureemart and Dr. Jesseda Chureemart working on the development of advance models to investigate heat assisted recording media (HAMR) properties. HAMR represents the future high density recording technology and is expected to be launched by Seagate soon.

Previously I have been a PhD candidate at the University of York in the Computational Magnetism Group led by Prof. Roy Chantrell and Dr. Richard Evans on a project focused on the investigation and characterisation of the magnetic properties of magnetic random access memory (MRAM) devices using an atomistic spin model. MRAMs, in particular spin-transfer torque (STT) MRAMs are new real candidates to replace the current memory devices providing lower power consuption and higher efficiency, hence a full characterisation and optimisation of this technology becomes of primary importance and relevance.

About me

When I am not researching in physics I enjoy reading, playing music and above all practicing some sport activity. In particular I love football, both playing and teaching it, swimming (I joined the Master swimming movement) and running some average distance such as 10 km and 10 miles. I also really enjoy travelling around the world discovering new places and cultures.
