**Estefania Artigao** (Ph.D.) has been working on the Condition Monitoring of Wind Turbines for over 8 years. She is currently a Research Fellow and an Associate Lecturer at the University of Castilla—La Mancha (UCLM), Spain. She studied Industrial Engineering (BS.c. and MS.c.) at UCLM. During her studies, she was granted an Erasmus Scholarship to study at the University of Modena and Reggio Emilia (Italy) and a Leonardo Scholarship at the University of Birmingham (United Kingdom). After her studies, she moved to Cambridge (UK) where she started her career as a researcher in the Wind Industry. She spent 2 years at TWI Ltd followed by 4 years at Brunel Innovation Centre, both companies based in Cambridge (UK). In July 2015, she moved back to Spain to join the Marie Curie Program under the H2020 AWESOME Project as an Early Stage Researcher where she completed a four-month Industrial Secondment at Ingeteam Service (Albacete, 2016) and a three-month Academic Secondment at the University of Strathclyde (Glasgow, United Kingdom, 2018). In November 2018, she obtained the Cum Laude Ph.D. Degree with European mention, entitled "Current Signature Analysis to Diagnose Doubly-Fed Induction Generators of In-Service Wind Turbines". Her field of research is advanced diagnosis of wind turbines, focusing on electrical analysis.
