Filipa Sequeira, PhD in Physical Engineering by University of Aveiro (2020) - Intensity based POF sensors for water quality assessment (SFRH/BD/88899/2012), financed by the Portuguese Foundation for the Science and Technology. Completed the Master in Applied Physics (2008) and Graduation in Teaching of Physics and Chemistry (2005) by the same university. Published 10 articles in peer-reviewed journals, 2 book chapters and 20 presentations in international conferences. Has received one Certificate of Excellence group award by SPIE. After completing her PhD, Filipa worked as a researcher at Instituto de Telecomunicações (IT-Aveiro) in the project AQUATICsens - wAter QUAlity assessment using Fibre OpTICs SENSors, making use of low-cost POF sensors for contaminants detection in water and was co-supervisor of a BSc student, under the same subject. Filipa had a career break of around two years, due to maternity leave and family assistance. Worked as a Senior Technician in Curricular Enrichment Activities (AECs), in part-time, and after as a Researcher at Instituto de Telecomunicações in Aveiro, collaborating with Mar2Protect and Alert-PFAs European projects, which aim real time monitoring of PFAs with optical fiber based chemical sensors. Filipa also collaborated with international teams in the development of new configurations of optical fibre chemical sensors for the detection of contaminants in aqueous matrices, with non-formal supervision of three doctoral students. Her research interests are related with increasing awareness for sustainability using optics and photonics, namely fibre optics sensors for contaminants detection in water.
