**Meet the editor**

Dr. Christian Cuadrado-Laborde received his Ph.D. degree in physics from La Plata University (UNLP, Argentina, 2005), and his Electric and Electronic Engineer degree from the San Luis University (UNSL, Argentina, 1998). Then, he joined to the most important federal research agency in Argentina (CONICET, 2005); where he is actually an Associate Researcher. He is currently also

an Associate Professor of the La Plata Catholic University (Argentina). He has served also as an Assistant Professor of the Faculty of Engineering of the UNLP. He was awarded by the Spanish Ministry of Science with a research fellow position to join to the Optical Fiber Laboratory group headed by M. V. Andrés of the Valencia University (Spain) during 2008-2009. Since then, he has a fluid collaboration with this research group. He serves also as a reviewer for several well-known journals of the Optical Society of America, the IEEE, Elsevier, SPIE, and the Electromagnetic Academy. He has published several papers in top-tier scientific journals such as Optics Letters, Laser & Photonics Reviews, Optics & Photonics News, etc. His current research interest includes fiber optics applications, photonic processing, and all-fiber lasers.
