You think looting is bad in Egypt, look at Peru, India, China. I've been told in China there are over a quarter-million archaeological sites, and most have been looted. This is a global problem of massive proportions, and we don't know the scale.

If you look at the Nile on a map of Egypt, you don't think it has moved very much, but the river is very violent and has moved over time.

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.

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.

There are so many previously unknown sites and structures all over the world. And I think most importantly 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.

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