João Lopes completed his M.Sc degree in Mechanical Engineering in November, 2019. In 2020, he was awarded with a scholarship from Fundação para a Ciência e a Tecnologia and currently he is a PhD candidate at NOVA School of Science and Technology (FCT NOVA). João's research is based on the microstructural and mechanical characterization High Entropy Alloys (HEAs) welded joints in similar and dissimilar combinations. Beyond the most common metallurgical analysis techniques such as Scanning Electron Microscopy (SEM), other characterization methods such as thermodynamical simulations and synchrotron x-ray diffraction are employed in the development of his work. Likewise, he has participated in 6 beamtimes at the DESY Synchrotron Facility (Germany). Until now, he has published 4 scientific articles in international peer-reviewed journals. His interests also lie in welding metallurgy of Shape Memory Alloys (SMAs), Additive Manufacturing (AM) and machine development.
