> ABOUT_ME
I am a postdoctoral researcher and teaching staff at the University of Helsinki.My expertise lies at the intersection of computational linguistics, machine learning, and trustworthy AI. I have developed and deployed novel methods for multilingual representation learning, modular translation architectures, systematic hallucination detection, and uncertainty quantification in generative models.
Prior to my PhD (2023), I earned an MSc in Mathematical Modelling from Università degli Studi dell'Aquila (2017) and a BSc in Applied Mathematics from ITAM, Mexico (2015).
