Since 1968, he worked in the Maya lowlands at the following sites in Belize, Central America: Lubaantun (1970–1971), Nohmul (1973–1986), Cuello (1975–2002),[5][6] and La Milpa (1992–2002). As well as specialising in the archaeology of Maya lowland sites in Belize, he has written on the emergence of complex societies in general, and on the history of archaeology.
He has worked on the editorial boards of Ancient Mesoamerica and the Journal of Field Archaeology. He has also been the archaeology correspondent for The Times newspaper in London.
In 1998 he was elected as a corresponding Fellow of the British Academy (FBA), honouring his contributions to the field of Mayanist research.[2][4]
