Alina Álvarez Larrain holds a Bachelor´s degree in Anthropology (2009) and a PhD in Archaeology from the University of Buenos Aires (UBA) (2015), Argentina. Currently she is a Postdoctoral fellow at the Research Center in Environmental Geography (CIGA) of the National Autonomous University of Mexico (UNAM), investigating local spatial knowledge and perceptions of archaeological landscapes in localities of Mexico and Argentina. She has been a PhD fellow at the National Scientific and Technical Research Council of Argentina (CONICET) between 2009 and 2014 studying settlement patterns and the construction of landscapes in the Calchaqui Valleys of Argentina. Since 2005 she has been a researcher at the Yocavil Archaeological Project at the Ethnographic Museum "J. B. Ambrosetti" (UBA). Her research focuses on the study of the landscapes and pre-Hispanic architecture of farmer populations of the Argentine Northwest. She has published 17 articles in national and international scientific books and journals with peer review, as well as 15 presentations at national and international scientific meetings. Her works included use of remote sensing, GIS, settlement patterns, ceramic and rock art analysis. Catriel Greco holds a Bachelor´s degree in Anthropology (2007)  and a PhD in Archaeology from the University of Buenos Aires, Argentina (2012) , where he also worked as assistant teacher for 5 years. Currently is researcher of the National Scientific and Technical Research Council of Argentina (CONICET) at the Department of Geology, National University of San Luis (UNSL). He has been a fellow of CONICET between the years 2007-2012, which allowed him to carry out his doctoral research on temporality and spatiality in the archaeology of the Calchaqui Valleys of Argentina. He was a postdoctoral researcher (2013-2015) at the Research Center in Environmental Geography (CIGA) of the National Autonomous University of Mexico (UNAM). He has also participated in research and extension teams at the national universities of Buenos Aires, San Luis and Mexico.
