My 3-month internship in O2 at UFF was my first long experience abroad. During this exchange, I had the chance of testing my scientific knowledge while working on a challenging project with Prof. André Belém, which consisted of the conception of an underwater ROV for undersea exploration. I could also test my adaptability to a foreign environment, which was made easy thanks to the welcoming community of UFF and especially O2 and Lammoc. Muito obrigado por esta experiência!
