About me

I am an Assistant Professor of Language Teaching, French and English Linguistics at Universidad Central del Ecuador, in Quito.

Currently finishing my PhD at KU Leuven ( ITEC, an imec research group) and UCLouvain ( CENTAL team) in Belgium, I work on dialogue-based CALL, more precisely on task-oriented dialogue systems (chatbots) for language learning, at the intersection of computer-assisted language learning (CALL) and natural language processing (NLP). My research focuses on the instructional design and the evaluation of the effectiveness of dialogue-based CALL systems for L2 proficiency development, in particular L2 fluency.

I am a PhD candidate in Linguistics thanks to a SENESCYT scholarship (Ecuador). Previously, I worked as a research assistant at UCLouvain on reflexive writing in general education.
