Combining physics, statistical methods, and machine learning

I am a cosmologist working with the Dark Energy Survey, DESI, and Euclid.

I also write science articles at The Times.

Cosmological inference

There is a lot we do not understand about the Universe: dark matter, dark energy, neutrinos, and the details of cosmic inflation. We are also faced with apparent tensions between observations at different cosmological times. I use novel statistical techniques to answer these questions using data from galaxy surveys.

Machine learning for science

Scientific inference problems are very different from many applications of machine learning and artificial intelligence. Problems are often data-scarce and we need a good understanding of our uncertainty to make scientific conclusions.
