Seeking to deepen my knowledge of computational fluid mechanics, I joined a research group dedicated to predicting the behaviour of a synthetic heart valve through numerical simulations. It was a project with a direct impact on healthcare, capable of testing a critical medical device and increasing the chances of success for patients with aortic valve dysfunctions. The group was composed of both Argentine and Brazilian researchers, and the language differences posed communication challenges. This experience allowed me to refine my interpersonal skills while significantly improving my Spanish and English.
