About Me.

I was born and raised in Manaus, a 2+ million people city in the heart of the Amazon rainforest. It was during my undergrad studies in Manaus that I learned that rivers have a story to tell. Since then, I couldn't stop thinking about the evolution of the Earth's surface and what hidden stories I could uncover by studying landscapes.​ Inspired in the Earth’s amazing scenery, I am intrigued by the processes that interact to create, sustain, and modify landscapes through time.

Below you'll find more about my path in this pursuit of speaking the language of landscapes. Click the box below to download my full CV.
