Astrophysicist ·Data scientist ·Science communicator
We can't make progress on what we can't see. I've spent my life uncovering signals buried in noise: tiny ripples in spacetime, meaningful insights within vast datasets, and the invisible pain of billions of humans and other animals. I use data and technology in creative ways to reveal these hidden stories, so we can ultimately reduce suffering in the world.
I'm Principal Data Scientist at Our World in Data, a publication that reaches tens of millions of readers every year. I'm also the creator of AltruFísica and serve on the board of the Welfare Footprint Institute. I hold a PhD in astrophysics, and I've pledged 🔸 to donate 10% of my income to effective charities.
