Valeria Pinti


My name is Valeria Pinti and I have a degree in physics and a PhD in environmental science at ETH Zürich. I love reading and writing, my second novel was published last year.

I strongly believe in a project like Little scientists, we live in the digital era: computation will be part of our children future and will certainly help them in their everyday life.

As a mother I find very important learning now how to actively use, recognize and implement the programming skills they'll learn with us.
