Astrid Schwegler Castañer has a BA degree in English Philology and an MA degree in Modern Languages and Literatures from the University of the Balearic Islands. In 2016 she obtained a predoctoral research grant with which she completed in 2020 her doctoral thesis on culinary discourses in the work of Asian-Australian authors with the highest distinction.

Her research, focused on the representation of food and discourses on food in literature and visual arts, has been presented at numerous conferences, mostly international, financed with scholarships and travel grants awarded by different associations. Her work has led to publications in international indexed journals such as Continuum: Journal of Media & Cultural Studies, Journal of Postcolonial Writing, and Feminist Media Studies. Her research has culminated in the acceptance of a monograph by Brill with publication planned for 2024.

In 2016 she joined the R+D project working team 'The politics, aesthetics and marketing of literary formulae in popular women's fiction: History, Exoticism and Romance' (FFI1206-75130-P) financed by the Ministry of Economy and Competitiveness until late 2020. As part of the project, she participated in academic and knowledge transfer activities, in addition to completing an article on the use of food in popular romance that is being reviewed.

In 2022 she joined the R+D project 'Romance for Change: Diversity, Intersectionality and Affective Reparation in Contemporary Romantic Narratives' (PID2021-122249NB-I00) financed by the Ministerio de Ciencia e Innovación until the end of 2025. Along with Dr. Paloma Fresno Calleja, she was the main organizer of the international conference of the European Association for the Study of Australia (EASA) that took place in Palma in September 2023. She is currently working on the connections between romantic relations, diversity and social change in Asian diasporic texts such as Vivian Pham's The Coconut Children and Esther Yi's Y/N.
