#### **Catalin Constantinescu**

Dr. Catalin-Daniel Constantinescu is a senior scientific researcher affiliated with the CNRS (Centre National de la Recherche Scientifique) in Marseille, France. His research interests cover aspects related to laser and plasma processing of materials, particularly for developing thin films and nanostructures, with applications in microelectronics, photonics, and electrical engineering. Three main processing techniques are worth mentioning, including pulsed laser deposition (PLD), matrix-assisted pulsed laser evaporation (MAPLE), and laser-induced forward transfer (LIFT). However, several other physical/chemical deposition and processing methods, as well as lithographic methods, should be noted as well, such as colloidal lithography using an adapted Langmuir–Blodgett technique and laser dewetting.

With 77 published papers, 1,037 citations, and an h-index of 21 (Scopus, July 2023), the research of Dr. Catalin-Daniel Constantinescu covers various aspects of materials sciences, due to his background in chemistry, physics, and engineering. He has also co-organized several conferences and symposia, including the EMRS 2021 Spring Meeting (symposium H—Laser material processing: from fundamental interactions to innovative applications), has delivered over 100 lectures and speeches at national/international meetings in over 15 countries, and is a member and chairperson of different international conferences, a member of different expertise and jury committees, and an editor. He has coordinated several regional, national, and international research projects, including two European infrastructure project proposals, and has actively participated and/or organized several events to promote science to the public, including "Fete de la Science" and "La Nuit Europ ˆ eenne des ´ Chercheur·e·s".

#### **Lucian Petrescu**

Dr. Lucian-Gabriel Petrescu is a tenured Professor at the Politehnica University of Bucharest, Romania. With over two decades of teaching activities and research projects, his main research interests focus on magnetic materials' characteristics using vibrating-sample magnetometers (VSMs) and single sheet testers (SSTs) in order to connect magnetic properties with their engineering utility. Another important aspect of his research is related to the modeling of magnetic materials using different models for predetermining power losses at a high frequency.

Dr. Lucian-Gabriel Petrescu is an author of 79 research papers published in prestigious journals or presented at international conferences. His work has over 206 citations, with an h-index of 9 (Scopus, July 2023). He has led 4 research projects and been a part of 17 other national research projects and 1 international research project. He is the leader of the "Technical Magnetism Laboratory" at the Politehnica University of Bucharest.
