Dr. Aleksandra Baron-Wiechec's background is in materials science and for last years she has been working in the area of electrochemistry and surface analysis. Her career path is a good example how relatively not related scientific activities can lead to plasma physics fascination and to Culham Centre for Fusion Energy. She completed her Ph.D. and held a position as an assistant professor at the Silesian University of Technology in Gliwice, Poland since 2005. At that time she studied amorphous metallic materials along with their corrosion behaviour.
She joined the School of Materials at The University of Manchester in 2008 as a Marie Curie Fellow. During that time she was also a frequent user of the Van de Graaff accelerator at the Université Pierre et Marie Curie in Paris. Thanks to the Marie Curie project she got an opportunity to perform unique multidisciplinary experiments on the edge of electrochemistry and nuclear physics.
After finishing Marie Curie fellowship in 2010 she joined the EPSRC Programme Grant and she continued her scientific adventure working on plasma electrolytic oxidation in Manchester. It was turning point in her scientific life since she discovered plasma physics during anodizing pieces of Mg by applying very high AC current. Combined comprehensive hands-on experience in studying surface of materials and more importantly transferable skills, gave her an important confidence for moving to CCFE in December 2012 and being a scientist in this demanding environment.
