Matheus A. Tunes is an Assistant Professor in the Department of Metallurgy at the Montanuniversität Leoben, where he leads the Laboratory of Metallurgy in Extreme Environments. He earned his PhD in Atomic Collisions in Solids and Electron Microscopy from the MIAMI Facilities atthe University of Huddersfield (UK) in 2020, following a Master of Science degree in Metallurgical Engineering and Materials Science (2015) and a Bachelor in Physics (2012) from the University of São Paulo (Brazil). Withan international career focused on materials in extreme environments, his expertise spans materials for fission and fusion reactors, nuclear microreactors for space and mobile applications, as well as lightweight materials for space applications. He was an ASTRO fellow at the Oak Ridge National Laboratory and, in 2021, received a prestigious Director’sFellowship from the Los Alamos National Laboratory. He is the 2020recipient of the Ion Beam Materials and Modifications (IBMM) early career award. In Leoben, he leads a diverse, highly motivated, and internationally recognized research team focusing on materials for thermonuclear fusion reactors, space, hydrogen energy, hypersonic, and corrosion-resistant applications.
