The workshop was organized linguists from the Universidad Nacional Autónoma de México (UNAM) and Colegio de México: Ana Aguilar Guevara, Renato García González, Samuel Herrera Castro, Julia Pozas Loyo, Rodrigo Romero Méndez, Violeta Vázquez-Rojas Maldonado. It brought together undergraduate and graduate students (see picture-2) doing research on (and in many cases speaking natively) 17 different indigenous languages of Mexico along in addition to Spanish and Mexican Sign Language.
The workshop took place at the new Unidad de Extensión UNAM in Oaxaca as well as in the scenic Centro Cultural San Pablo at the Biblioteca de Investigación Juan de Cordova. As you can see in the photo below (picture-2), the semantics gods in this ex-convent first built in 1529 were behind the class as they worked towards generalized quantifiers on the last day of the course!
