About the event
Dr. Melissa Röhrig is a Brazilian materials scientist specializing in the processing, microstructural and magnetic analysis of rare-earth permanent magnets. She holds a PhD in Materials Science and Engineering and has worked on projects supporting the implementation of the rare-earth production chain in Brazil. Currently, she is a researcher at the Max Planck Institute for Sustainable Materials in Germany, where her work focuses on improving the corrosion resistance and recyclability of Nd-Fe-B magnets — critical components for green energy technologies. Her research on
corrosion specifically explores the effects of cryogenic treatment as multi property tool. Melissa is passionate about sustainable materials design and fostering interdisciplinary collaboration.
