Luiz Tizei has a Bachelor in Physics (2005) from the Universidade de Campinas, Brazil, and in 2011 he obtained his PhD, from the IFGW at UNICAMP, with a thesis concentrated on the chemical and physical properties of III-V semiconductor nanowires. He then joined the STEM group at the Laboratoire de Physique des Solides (LPS), Orsay, France, for a post-doc between 2011 and 2013, during which he built a light intensity interferometer to detect single photon sources excited by fast electrons (cathodoluminescence) in an electron microscope. Between October 2013 and December 2014 he worked with at the AIST-Tsukuba on electron spectroscopy of individual atoms, molecules, and atomically thin layers. In December 2014 he was hired by the CNRS to work at the LPS. His research is focused on the development of electron spectroscopy techniques and their application to nano-optics.

Patricia Abellán received her BSc in Physics from the Aalborg University (Denmark) and her Ph.D. in Materials Sciences from the Autonomous University of Barcelona and Institute of Materials Science of Barcelona (ICMAB-CSIC), Spain, in 2011. She has held postdoctoral positions at the University of California – Davis and Pacific Northwest National Laboratory, USA and a staff scientist position at SuperSTEM Laboratory (Daresbury, UK). Currently, she is a CNRS researcher (tenured) at Institute of Materials Jean Rouxel (IMN), at Nantes University. Her research focuses on the study of defects at interfaces on functional materials and their relationship with properties using electron microscopy and on the use of the effect of the electron beam in solid and liquid media to investigate nanomaterials properties.

Sonia Estrade obtained a Degree in Physics (2005) and a PhD in Nanoscience (2009), all of them at Universitat de Barcelona. She is currently a Professor at the Department of Electronic and Biomedical Engineering of UB. Her main research interest focuses in EELS applied to semiconductors for photovoltaic and photonic devices to complex oxides for energy production or sensing applications. She is currently applying big data analytics to EEL spectra for advanced materials characterization. She is also the president of the Gender Equality Commission of the Faculty of Physics at UB, and the president of AMIT-Cat.

Gabriel Sánchez  Santolino received his BSc and Ph.D. (2015) in Physics from the Complutense University of Madrid. During his Ph.D., he also carried out part of his research at the STEM group at Oak Ridge National Laboratory. He then joined the Crystal Interface Laboratory at the University of Tokyo as a postdoctoral researcher from 2015 to 2017. In 2017, he obtained a Juan de la Cierva postdoctoral fellowship and joined the 2D Foundry group at the Spanish National Research Council in the Institute of Materials Science of Madrid. In 2019 he joined the Eva Olsson Group at Chalmers University of Technology. From November2019, he is a Jóvenes Investigadores (JIN) Researcher at the Department of Materials Physics at the Complutense University of Madrid. His main research interest is the direct visualization of local electromagnetic field structures by Differential Phase Contrast Scanning Transmission Electron Microscopy (DPC-STEM), and four-Dimensional Scanning Transmission Electron Microscopy (4D-STEM) for diffraction and phase contrast imaging.

María Varela del Arco has a doctorate (2001) in Physics from the Complutense University of Madrid. In 2002, after obtaining her doctorate, she joined the Solid State Division of Oak Ridge National Laboratory (Tennessee, USA) with a prestigious Wigner Fellowship contract. In 2011 she returned to Spain as a tenured professor at the UCM Faculty of Physical Sciences after receiving a Starting Investigator Award from the European Research Council. She currently holds a full professorship in the area of condensed matter physics since 2017, and has extensive experience in the characterization of low-dimensional systems such as thin films and superstructures of complex materials of interest in spintronics and magnetism. She is an internationally renowned expert in electron microscopy and spectroscopy. In 2014 she received the prestigious Burton Medal from the Microscopy Society of America, and in 2016 she was named a fellow of the American Physical Society.
