About me

I am a PhD candidate in Natural Language Processing (NLP) at the University of Sheffield. I started at the Speech and Language Technology (SLT) Centre for Doctoral training (CDT) in September 2021. My focus lies in numerical reasoning especially how to evaluate and improve smaller accessible general-prupose model to enhance their numerical understanding in downstream tasks. My background is in mathematics and previously I was a mathematics teacher in a secondary school. I also taught French and English in Colombia.

Outside my work, I enjoy salsa dancing and other latino style dances. I have also started to knit. But above all, I love travelling and get to experience different cultures.
