Alicia's research utilizes bioarchaeological methods to investigate the transition to agriculture, the rise of urban economies, and resource exploitation strategies employed by pastoralists.
Her current research decouples social complexity from subsistence, where domesticates are considered an essential ingredient in the construction of social hierarchies. Through multiple lines of evidence, including analyses of dental pathologies and stable isotopes, she demonstrates variation in the economic trajectories of pastoral groups with diverse socio-political configurations. Adopting a biochemical approach, her work provides direct evidence of human landscape use alongside domesticated livestock. Alicia's research demonstrates a link between population growth and the emergence of social stratification within societies engaging in effective forms of niche construction, turning ecological difficulties into advantages.
