Mirco Peron earned his degree in mechanical engineering (summa cum laude)

in 2015 from the University of Padova, where his thesis evaluated the fatigue

damage and stiffness evolution in composite laminates. He is currently a PhD

student at Norwegian University of Science and Technology (NTNU), Trondheim.

His PhD topic deals with the optimization of mechanical and corrosion

properties of magnesium and its alloys for biomedical applications, with particular

reference to the corrosion-assisted cracking phenomena.

Filippo Berto is Chair of Structural Integrity at the Norwegian University of

Science and Technology in Norway. He is in charge of the Mechanical and

Material Characterization Lab in the Department of Mechanical and Industrial

Engineering. He is author of more than 500 technical papers, mainly

oriented to materials science engineering, the brittle failure of different materials,

notch effect, the application of the finite element method to the structural

analysis, the mechanical behavior of metallic materials, the fatigue performance

of notched components as well as the reliability of welded, bolted and

bonded joints. Since 2003, he has been working on different aspects of the

structural integrity discipline, by mainly focusing attention on problems

related to the static and fatigue assessment of engineering materials with particular

attention to biomedical and medical applications and materials.

Jan Torgersen is Professor of mechanical engineering at NTNU, Trondheim.

He received his PhD from Vienna University of Technology, where he worked

on high-resolution laser microfabrication of hydrogels for tissue engineering.

He was pioneering in the work of processing hydrogel formulations at micron

scale resolution in vivo, in the presence of living cells and whole organisms.

He received a postdoctoral fellowship to work on a nanoscale vapor deposition

technique called atomic layer deposition, allowing conformal coating of

thermally fragile and nanostructured substrates with atomically thin layers of

a wide range of materials. He contributed to the development of a selflimiting

deposition process for high-k materials for Dynamic Random Access

Memory (DRAM) applications. His current research interests are micro- and

nanofabrication as well as surface functionalization, with particular focus on

biomedical applications.
