Esperanza Habinger is a fan of science. She studied medicine and then specialized in child and teen psychiatry. Esperanza has always been interested in sharing this knowledge, and that’s why she’s taken part in many conferences through the Society of Child and Adolescent Psychiatry. She is currently the vice president of the Chilean Society of Bipolar Disorders, but what she is most passionate about is talking with kids and teenagers about how they feel and what problems they have. This is her first science book for young readers. Esperanza lives in Santiago, Chile.
