Elizabeth Graham is a Professor of Mesoamerican Archaeology at UCL. She has worked, for decades, on the Maya civilization, both in prehispanic and colonial times, specifically in Belize. She has recently turned her attention to Maya Dark Earths, and conducts pioneering work in the maya region as dark earths have mostly been studied in the Amazonia. She particularly focuses on how human occupation (domestic and industrial waste, burials, abandoned houses and processing sites) influences soil formation and production.
