Mariona Guijarro (Palma, 1993) is a biochemist, sexologist, and sexual and menstrual educator. Her critical and social perspective led her to reject a future in biomedical research, citing its academic nature and its "patriarchal and sexist perspective on medicine and other branches of science." She decided to pursue studies promoting gender equality, and the more she researched, the more she realized that "everything had to do with sexuality." And everything is also "how men and women have historically been described and what roles society has imposed: men who are promiscuous by nature and single-parent women, also by nature." She is currently specializing in the Philosophy of Science and delving into the intersection of scientific research, sexism, and other oppressions.
