Marina Castaneda, psychotherapist, author and lecturer, was born in Mexico City in 1956. She has lived in Mexico, the United States, France, Switzerland and Egypt. Trilingual and of a decidedly interdisciplinary bent, she has studied literature, history, psychology and music at Harvard, Stanford, and the Ecole Normale Superieure of Paris, among others. Since 1988, she has devoted herself to the practice of psychotherapy in Mexico City and Cuernavaca. She has published over 300 articles on psychological, political and social topics, and regularly presents lectures and courses throughout Mexico. She is a frequent guest on radio and television programs. Her book on the psychology of homosexuality was published in France by Robert Laffont, under the title Comprendre l'homosexualite (1999), in hardback and paperback, as well as in Italy; its Spanish version, La experiencia homosexual , was published in Mexico by Editorial Paidos (1999), and is now in its 9th edition. In El machismo invisible (Mexico City, 2002; new edition, 2007; Brazil, 2006), she analyzed another controversial topic of both psychological and social interest. Her most recent book, La nueva homosexualidad (Paidos, 2006) examines various social, economic legal and cultural aspects of homosexuality today. A psychological thriller, Amores virtuales, appeared in 2010 (Mexico, Random House Mondadori); and, in April 2011, an essay on the psychological and social aspects of listening, entitled Escuchar(nos), published in Mexico by Taurus.
