I’m a Research Scientist (Postdoctoral Researcher) at the University of Copenhagen, working on large multimodal models for video and language understanding. My current research focuses on model development, evaluation, and real-world applications of vision-and-language systems. 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 from Latin America and other underrepresented communities in AI.
