Professor Anthony Challinor

Prof. Anthony Challinor, MA, PhD. Bye-Fellow (Physics). Professor of Cosmology and Astrophysics.


I have a range of research interests in physical and theoretical cosmology, mostly centred on the issue of testing the cosmological model and the origin of cosmic structure with cosmological observations. A particular focus is the the origin, interpretation, and measurement of temperature anisotropies and polarization in the CMB. I was a Core Team member of the Planck High-Frequency Instrument and am a member of the Simons Observatory with particular interests in lensing of the CMB, constraining the key cosmological parameters and searching for B-mode polarization induced by gravitational waves from the early universe.


I am Professor of Cosmology and Astrophysics at the University of Cambridge and Deputy Director of the Institute of Astronomy and the Kavli Institute for Cosmology, Cambridge. I currently lecture Relativity in Part-II Physics. I have also acted as Senior Examiner for NST IA Mathematics, NST IB Mathematics and NST II Astrophysics. I am a member of the Teaching Committee at the Institute of Astronomy. I have also supervised 12 PhD students and one MPhil student.
