Biography

I successfully obtained the degree in Biology at the University of Girona (2007–2011) and my master’s degree in Biodiversity Management at the Autonomous University of Barcelona (2011–2012) with two scientific articles in peer-review journals. I became a research assistant at the University of Girona working in metacommunity ecology and habitat conservation. I published two scientific articles in peer-reviewed journals and gained ample experience in field research and the taxonomic expertise of freshwater biodiversity. I started my PhD (2013) with a part-time grant at the University of Vic-Central University of Catalonia (UVic-UCC). I was awarded with several scholarships to conduct my research in leading European and Asian institutions, and to develop complementary skills in experimental research, academic practices, and methodological techniques. I successfully obtained my PhD thesis (2017) with four scientific publications, four research stays in international research institutions, three international and national talks, seven seminars and workshops, and 750 hours of teaching courses. I was immediately awarded with a full career grant (2017–2019) as a postdoctoral researcher at the University of Concordia (Montreal, Canada) to work on North American fish diversity and to master community ecology analyses. I was then awarded with a six-month career grant (2019–2020) at UVic-UCC aimed to model the human impacts on the sustainability and conservation of riverine fish communities in a Mediterranean climate region, to supervise PhD students, and the results are published in two peer-review journals. I was awarded with a full career grant (2020–2022) at Paul Sabatier University (Toulouse) and I am currently working on the spatiotemporal dynamics of freshwater fish communities, while I am supervising two PhD students.
