I am a cosmologist using observations of the relic light from the Big Bang, the cosmic microwave background (CMB), to constrain the properties of the Universe.

Here at Cardiff, I am an STFC Ernest Rutherford Fellow and Lecturer working between the Astronomy & Astrophysics and the Astonomy Instrumentation groups.

My research combines theoretical work with statistical data analysis to answer fundamental questions about the Universe. I lead work on characterising multi-frequency CMB microwave data, on combining data from satellite and ground-based experiments, and on extracting the underlying primordial CMB signal carrying the imprint of the physics of the early Universe, leading to state-of-the-art constraints on neutrino physics, inflation, dark matter and dark energy physics.

I am a member of many CMB experiments: I am a long-standing science member of the Atacama Cosmology Telescope, a Scientist of the Planck mission, and a full member of the Simons Observatory for which I lead pipeline development for characterizing small-scale data and serve on the Theory and Analysis Committee. I am a full member of the proposed, Japanese-led LiteBIRD mission for which I also serve as UK National coordinator and European Deputy Spokesperson for LiteBIRD-Europe.

I am also a full member of the LSST Dark Energy Science Collaboration, and a member of the Euclid Collaboration, looking at how to combine low-redshift data with the CMB.

  • Christiane Lorenz, PhD student at the University of Oxfrod (2016-date) -- constraining neutrino physics and dark energy with low- and high-redshift data.

During 2013-2017 I have served as Advisor for graduate students at Wolfson College, Oxford.
