Okay, so Roland Robertson is a really smart person who likes to study things. He likes to study how people and things from different parts of the world connect with each other.
Imagine you have a bunch of toys that all look different and come from different places. Robertson likes to look at how those toys relate to each other, even though they are different. He also looks at how the people who play with the toys talk to each other and share their ideas.
Robertson is very interested in something called globalisation, which is when ideas, people, and things move around the world faster and more easily than they used to. He thinks that this is really important to study because it can change the way we live and think about the world.
Basically, Roland Robertson is like a detective, but instead of solving mysteries, he tries to understand how the world works and how it affects us.
