Isabel Marín Beltrán completed her PhD in Marine Sciences at Universitat Politècnica de Catalunya (Barcelona, Spain) in July 2017. During her PhD, Isabel studied the effect of anthropogenic and mineral aerosols on bacterial communities of the Mediterranean Sea, acquiring expertise in the areas of Marine Biochemistry and Microbiology. She has a MSc Degree in Marine Sciences at the Universitat de Barcelona, where she conducted a project on the determination of Caretta caretta foraging areas within the Mediterranean Sea, based on their isotopic signature. She completed the BSc in Marine Sciences at Universidad de Cádiz (Cádiz, Spain), after studying Geology (BSc, 3 years) at Universidad de Zaragoza. In 2019, Dr. Marín-Beltrán got a CEEC individual postdoctoral fellowship (junior researcher) in the framework of the FCT - Scientific Employment Stimulus program (project "MASS": Microplastics in the Aquatic Environment; Code: CEECIND/03072/2017). In this project, she is evaluating potential sources of microplastics to the coastal environment, such as atmospheric deposition, as well as looking for environmentally safe solutions to remove microplastics from the environment. Namely, by means of microbial communities and isolates coming from the marine environment and from wastewater treatment plants. The work is being developed at Laboratory of Environmental Technologies, at Centre of Marine Sciences (CCMAR), leaded by Professor Maria Clara Costa. Isabel has published 10 articles in high impact journals (among them, Science of the Total Environment, Marine Pollution Bulletin), 6 of which she is the first and/or corresponding author. She is currently preparing two other manucripts for prompt submission, and a chapter of a book aimed to the general public has just been submitted. She is also author of two "insight" comments published in the journal Science as part of the "NextGen Voices" series, and co-author of an invited book chapter. She regularly contributes to peer-revision on scientific journals such as Journal of Geophysical Research (Biogeosciences), Science of the Total Environment, or Marine Pollution Bulletin, among others. In addition, Dr Marín-Beltrán was invited to review a report prepared by the Instituto Português do Mar e da Atmosfera (IPMA) as part of the EU Marine Strategy Framework Directive, as an expert on marine debris. As PhD student, she participated in three (national and international) projects, and she was visitant student at Institut Méditerranéen d'Océanologie (MIO) of Marseille (France), at KTH Royal Institute of Technology of Stockholm (Sweden), and at Univeristà degli studi di Genova (Italy). After completing her PhD, she was visitant researcher at Heriot-Watt University (UK). As postdoc, she was research collaborator in one international (PROBIOMA) and one national, FCT-funded, project (METALCHEMBIO). She is currently part of an international (PLASTIC PIRATES) and one national (BIOEXTREMDEG) project. Dr. Marín-Beltrán has disseminated her research through 12 oral presentations in two national and 8 international seminars and conferences, included two invited talks. She has also presented her work through posters at several national (in Portugal and Spain) and 7 international conferences. Isabel has (co-) supervised the experimental work of >10 BSc and MSc students, and the final projects of 6 master students (one on-going). In addition, Isabel is very active as both organiser and participant of/at outreach activities aiming at transferring knowledge to the general public, especially to the youngest. She is also author of several videos aimed to promote the sustainable use of resources, available at: https://www.youtube.com/channel/UCJYY5LstRf4an1KLGMzvawA.
