Isol was born in 1972, in Buenos Aires, where she currently dwells.
She studied at the Escuela Nacional “Rogelio Yrurtia” to become a Fine Arts teacher, and spent a few years studying Art at the University of Buenos Aires, a career she finally abandoned to fully devote to her work as an illustrator for media and authoress of children illustrated books, a natural synthesis of her taste for artistic comic, literature and visual arts.

Her first book Vida de perros (A dog’s life) was published in 1997, following a Mention of Honour at the Contest A la orilla del Viento, organized by FCE publishers (Fondo de Cultura Económica, Mexico). From that moment on she has continued to publish books as an integral authoress, and has in turn illustrated texts written by other authors, such as Jorge Luján, Graciela Montes and Paul Auster.
Her personal style for telling stories by means of drawings (candid but ironical at a time) has seen the fortune of being published in Mexico, Spain, USA, France and Argentina.

Among other projects she has partaken of the BIB ‘99 Workshop for illustrators, organized by UNESCO in Slovakia, and has received the Golden Apple 2003 Award for her illustrations to the book Tic Tac.

Her books El Globo (The Balloon) and El cuento de Navidad de Auggie Wren (Auggie Wren´s Christmas Story) have been selected to be part of the White Ravens list 2003, and 2004, the latter involving a Special Mention.

Her book Tener un patito es útil (It´s useful to have a duck) was selected by the American Institute of Graphic Arts (AIGA) for their catalogue and exhibition"AIGA 50 Books/50 Covers" (USA). This book won also a Silver Mention in Quórum Awards (Designers Council from Mexico) and it was chosen for the Banco del Libro Best Books 2008 (IBBY Venezuela)

Nomineé for the Astrid Lindgren Memorial Award 2010 (Sweden)

Finalist in the Hans Christian Andersen Award 2006 and 2007 on behalf of Argentina (IBBY/International Board of Books for Young People, Switzerland)
