Annabel Fernandes graduated in Chemistry—Scientific Branch from the Faculty of Sciences, University of Portoin in 1999, and earned her MSc and Ph.D. in Chemistry from the University of Beira Interior (UBI) in 2003 and 2014, respectively. Between 1999 and 2011, she developed professional activity in industry, mainly in the area of quality and environmental management systems, according to ISO 9001 and ISO 14001. In 2012, she started an FCT-financed Ph.D. program (SFRH/BD/81368/2011) under the theme “Electrochemical treatment of sanitary landfill leachates” and, between 2015 and 2018, she benefited from a postdoctoral grant, financed by FCT (SFRH/BPD/103615/2014), under the theme “Sustainable treatment of effluents from urban wastes management”. She has been a researcher at UBI, FibEnTech Research Unit since 2018, and develops her research in the Chemistry Department. She develops studies in the field of environmental electrochemistry applied to the degradation of persistent organic pollutants present in real and simulated effluents, and also applies/develops analytical methodologies for the monitoring of environmental parameters during the treatments. More recently, she has been focused on the study and development of bioelectrochemical processes, aiming for sustainable treatment solutions in a circular economy approach.
