Mariella de Souza-Baker

In a nutshell, tell us about yourself.

I grew up just outside of London and had initially envisioned becoming a lawyer. I eventually learned that much could be done before communications broke down by learning more about how people communicate and what drives them. Working in Communications for the last decade has allowed me to develop ways to empathise with various groups and speak their language. Using it to face the greatest existential threat to our world is quite the compelling mission.

What’s the best part of your job?

Our team. I love the uniqueness, passion and diversity of our people, how we all get on across our cultures, I greatly value what we’re all building together and ultimately seeing the impact of our collective work.

What keeps you awake at night?

The cacophony of city living! And, thinking about how to end capitalism and colonial legacies. I often reflect on how I’d love to build a time machine and pick up Gandhi, MLK, Emmeline Pankhurst, Mandela, Angela Davis, AOC and all their pals to return to stop the imperialists in their tracks.

What do you most admire?

Oppressed groups fighting back,  female leaders, living thoughtfully and consciously in a world that rewards speed and limitless growth, and indigenous peoples maintaining their traditions and harmony with the world – we have much to learn.

What makes you laugh?

Blackadder, forever and ever.

When are you happiest?

When I’m anywhere with my amazing little family, backpacking, encountering new cultures and listening to personal tales and experiences.
