Gianni Pisa is currently a Ph.D. candidate specializing in Materials Science, working jointly at the École Nationale Supérieure d’Arts et Métiers (Arts et Métiers Institute of Technology) in Paris and the ONERA (French Aerospace Lab), within the Materials Department. He holds a strong foundational background in materials engineering, with a specialization in metallurgy, which he acquired at the Institut National des Sciences Appliquées (INSA) Lyon. Mr. Pisa’s research interests lie primarily in the field of Additive Manufacturing (AM) of metals. To date, his work has largely focused on Laser Powder Bed Fusion (L-PBF) processes. His ongoing doctoral research specifically investigates the melt pool instabilities that directly lead to defect formation in L-PBF.
