Julieta Fierro, fell in love with science since she was a child. She works at the Institute of Astronomy at UNAM and is a full member of the Mexican Academy of Language. She is dedicated to the dissemination of astronomy, has written books and articles for diverse audiences, has held exhibitions for museums, participates in mass media and gives lectures. She believes that science awakens curiosity, solves problems, fascinates and is a field of development where freedom dominates. She enjoys being with her family, spending time with her friends and loves universal culture, particularly art, history, music and classical and contemporary dance. Universal injustice hurts her. When she is sad, she reads science or literature and feels happy.
