Building on regional research into the ecological and economic aspects of settlement strategies in the central Conchucos region, Alexander Herrera turned to the study of mortuary and ceremonial landscapes across the Ancash highlands. His focus on identity and territory as colonial tools of archaeological discourse led him to address the role of archaeologists and the appropriation of archaeological knowledge in rural development projects and in heritage tourism. Currently he conducts research into symbolic and technical aspects of water management. He has lectured at Universidad de los Andes, Colombia, since 2006 and is currently a Fellow of the Commission for Archaeology of Non-European Cultures at the German Archaeological Institute. Recent books include: La recuperación de tecnologías indígenas: arqueología, tecnología y desarrollo en los Andes, and Arqueología y desarrollo en América del Sur: de la práctica a la teoría.
