In our Brilliant Minds series, Tomorrow Today presents young scientists from around the world who live and do research in Germany.  Cuban-born geologist Yamirka Rojas-Agramonte works at the Johannes Gutenberg University in Mainz. Her research centers on a few key questions: How did Cuba and the other Caribbean islands come into being? And what role have various continental plates played in the process? According to Rojas-Agramonte, research on the topic in Cuba is still in its initial stages. But in the future, the results of her work could play a crucial role in helping identify deposits of mineral resources.
