I keep being surprised by the amount of archaeological sites and features that are left to find all over the world.

We only have a limited amount of time left before many archaeological sites all over the world are destroyed. So we have to be really selective about where we dig.

We have so many issues with overpopulation and urbanization and site looting. And this isn't just Egypt. This is everywhere in the world, even in America. So we only have a limited amount of time left before many archaeological sites all over the world are destroyed.

We emphasise the features on satellite maps by adding colours to farmland, urban structures, archaeological sites, vegetation and water.

What satellites help to show us is we've actually only found a fraction of a percent of ancient settlements and sites all over the world... It's the most exciting time in history to be an archaeologist.

The most exciting part of what I do is understanding the scale of what we don't know. There are just countless archaeological sites all over the world, and one of the most important and best ways of finding them is using digital technology.
