I’m a Postdoctoral Researcher at the University of Copenhagen working with the LAMP group and affiliated with CoAStaL NLP and the Pioneer Center for AI. My current research focuses on model development, evaluation, and applications of vision-and-language models. I completed my Ph.D. in Natural Language Processing at the University of Sheffield (UK), supervised by Professor Nikos Aletras, with research spanning computational social science, political communication, and multimodal modeling. I also hold an MSc in Computer Science from Sheffield and a BSc in Computer Engineering from ITAM (Mexico City). Previously, I worked as a Research Associate in the SheffieldNLP group and as an Applied Scientist Intern at Amazon Alexa Shopping, where I focused on generative language models.
My research interests lie at the intersection of NLP, vision-and-language modeling, and socially impactful AI.
Outside of research, I enjoy yoga and pilates, and I’m passionate about mentoring students—especially women from Latin America and other underrepresented communities in AI. I have co-organized LatinX in AI Workshop at NAACL’24 and I am part of the core team of SomosNLP the Iberomerican NLP community.
