Leonardo A. Delgado has MSc in Environmental Technology awarded by Polytechnic Institute of Bragança (IPB), Portugal, and BSc/graduation in Environmental Engineering granted by Federal Technological University of Paraná (UTFPR), Brazil, and recognized by IPB. Additionally, he has a technical degree in Chemistry awarded by State Technical School ETEC-Dr. Celso Giglio, Brazil, and worked as laboratory assistant for one year in an automotive paint and varnish company (Arpol Red Spot, Brazil). During the undergraduate studies, he contacted with scientific research, mainly in three areas: (i) physicochemical characterization and sustainable studies of biodiesel, as part of three embraced projects, (ii) soil composition and preservation, in the context of a project, and (iii) development of sensors technology for indoor air quality monitoring in farming facilities, in the scope of his MSc dissertation. Projects on the biodiesel topic included: (i) two R&D projects as volunteer, and (ii) the Tutorial Education Program (TEP) PetAmb Conexões de Saberes as scholarship holder, focused on working on the triad of teaching, research and extension inside and outside the university, in which he did research on biodiesel, gave minicourses on biodiesel and office package, and organized events (seminars, academic weeks, lectures). The project on the soil topic included the University Extension Program Soil at School, in which he was volunteer, focused on raising awareness of the importance of studying and preserving the soil. Additionally, he participated in two other projects during the undergraduate studies as volunteer: a multiproject and a digital inclusion project at the non-governmental organization (NGO) MediAres, centered on bringing recreational activities to the needy community. Projects and MSc dissertation gave him the opportunity to make fourteen communications in conferences/symposiums/seminars: (i) twelve oral communications, being the speaker in seven of them, and (ii) two poster communications. He was also a member of the organizing committee of six symposiums/seminars. Moreover, he published two papers in scientific journals: (i) one about his MSc dissertation, in which he was the first author, published in Springer as part of the Lecture Notes of the Institute for Computer Sciences, Social Informatics and Telecommunications Engineering book series (indexed to Scopus, Q1 in Computer Networks and Communications category, https://doi.org/10.1007/978-3-030-45694-8_18), and (ii) a second one about biodiesel characterization, published in the Brazilian Archives of Biology and Technology journal (indexed to Scopus, Q2 in Multidisciplinary category, https://doi.org/10.1590/1678-4324-smart-2018000560).
