Astrophysicist Karín Menéndez-Delmestre, a recipient of the prestigious 2015 L’Oréal UNESCO ABC Prize for Women in Science in the realm of physical sciences, is committed to deciphering one of the universe’s most profound enigmas: dark matter. Born in Puerto Rico to a French mother and a Cuban father, Karín’s multicultural upbringing has made her fluent in four languages. Currently a professor at the Valongo Observatory at the Federal University of Rio de Janeiro, Karín pursued her physics studies at McGill University in Canada. She earned her doctorate in astronomy from the renowned California Institute of Technology (Caltech) in the United States and completed her post-doctoral studies at the Carnegie Observatories in Pasadena, USA. As a scientist, her primary goal is to chart the influence of dark matter’s gravitational pull within the Milky Way and predict its future impact on our galaxy.
