I am Niall Jeffrey, I am a Researcher at the École Normale Supérieure (ENS) in Paris, and also an Honorary Research Fellow at University College London. I am interested in cosmology, statistical methods and machine learning.

Combining these together we can learn about the Universe and understand Dark Energy & Dark Matter from cosmological data.

I am an active member of the Dark Energy Survey and the Euclid mission.
