My name is Adriana Márquez Colón, and I am currently pursuing a PhD in English Linguistics at the Complutense University of Madrid (UCM) under the supervision of Dr. Mario Serrano Losada. My research focuses on language ideologies, Spanish-English code-switching, and acceptability judgments in Puerto Rico.

I hold a Master’s degree in English Linguistics from UCM, where my research examined the relationship between language ideologies, demographic factors, and the acceptability of intra-sentential Spanglish among bilingual Puerto Ricans. Before moving to Madrid, I completed a Bachelor’s degree in English at the University of Puerto Rico, Mayagüez, where I first developed my interest in language variation and change.

In 2022, I worked with Dr. Patricia Nieves Sánchez and co-authored Content Standards and Grade Level Expectations for English: Developing Leaders for Success, published by the Puerto Rico Department of Education as part of the Luis A. Ferré Internship Program. During my undergraduate studies, I also worked as a research assistant and comparative editor with Dr. Eric D. Lamore on projects concerning nineteenth-century abolitionist literature and Atlantic literary networks.

In January 2026, I presented a poster on my doctoral research at the LIV Conference of the Sociedad Lingüística Española in Madrid. I am also scheduled to present at the Second International Symposium on Language Ideologies and Attitudes (IDEOLING 2) in Lleida in October 2026 and at BIUNED in Madrid in November 2026.

My doctoral research, provisionally titled Language Ideologies in Puerto Rico: A Mixed-Methods Study of Spanglish, expands on my Master’s research by examining how ideological and demographic factors interact in the evaluation of Spanish-English code-switching. The project combines acceptability-judgment tasks, language-attitude measures, and qualitative interviews. More broadly, my research seeks to bring experimental syntax and sociolinguistics into closer dialogue by examining how ideological, metalinguistic, and demographic factors contribute to variation in acceptability judgments.
