About the Authors


Damian Evans

A Canadian-Australian researcher, Damian Evans (d. 12 Sept 2023, Paris, France) focused on archaeological landscapes in mainland Southeast Asia, in particular those of the Khmer Empire. 

He specialized in using advanced remote sensing technologies such as airborne laser scanning (or LIDAR) to uncover, map and analyse the urban and agricultural networks that stretched between, and beyond, great temple complexes such as Angkor in Cambodia.

Fellow researcher with the University of Sydney, then the Institut Francais d’Etudes Asiatiques, then EFEO, he has published several essays on Angkorian archaeology and mapping.

In 2015, his team carried out the most extensive airborne study ever taken by archaeologists – using a laser radar mounted on a helicopter to scan an area of the jungle in Cambodia comparable in size to greater London”, read his obituary in The Guardian.
