Isabel Castiajo holds a degree in Classical and Portuguese Languages and Literatures (1999), a postgraduate degree in Classical Languages - Latin Teaching (2004), as well as in Classical Theater and its Reception (2005), and a Master's degree in Classical Studies (2009), all from the Faculty of Letters of the University of Coimbra. She is currently in the second year of her Ph.D. in Classical Studies - Ancient World at the same institution and collaborates as a researcher at the Center for Classical and Humanistic Studies of the University of Coimbra. Following her undergraduate studies, she taught Portuguese language (and occasionally Latin language) at various public schools (1999-2007), where she also held leadership positions such as Class Director and Portuguese Curriculum Coordinator, and, from 2011 to 2022, at CLIP - Oporto International School. Isabel Castiajo took a five-year hiatus from teaching to work as a Curricular Area Manager at Edições ASA - Grupo Leya (2007-2011), where she developed marketing strategies, organized educational events (e.g.,"Encontro Pedagógico ASA '09 – Novos Programas e Desafios da Língua Portuguesa”), and delivered presentations showcasing textbooks to school teachers around all the Portuguese country. Moreover, she published her Master's thesis, "O Teatro Grego em Contexto de Representação” (University of Coimbra Press, 2012), and authored educational materials including "Testes de Português" for grades 5, 7, and 8 (Edições ASA - Grupo Leya, 2007, 2013). She also co-authored curriculum materials for Portuguese language, including textbooks ("Novos Percursos profissionais", 1, 2 and 3; "Sentidos", 10th-12th grades, 1st-2nd editions) and a school support book ("Testes e Exame"). These were published between 2015 and 2023. Isabel's passion for theater began at age 15 when she performed with amateur theater groups (e.g., “Plebeus Avintenses” in Vila Nova de Gaia), and co-founded the “Associação Gaia Arte Estúdio (AGAIARTE)”, acting in various theater productions such as "As Vedetas" by Lucien Lambert, "O Urso" by Anton Tchekhov, or "O dia seguinte" by Luiz Francisco Rebello). She further participated as an actress at “Teatro Académico - CITAC” in Coimbra. Beyond acting, she has directed plays in various school settings and institutions (e.g., “P.O.D.E.P.I.” (Projeto de Luta contra a Pobreza) in Pinhel, Guarda) and wrote the script for the solo play "Fernando & Pessoas", in which she currently performs. Additionally, she lent her voice to musical projects like "Lápis" and "Narcotic - Tecido Humano" and even composed lyrics for Dan McAlister's musical compositions.
