Biographic Notes
Andrew Liddle is a researcher at IA. He was awarded a first degree in Physics and Mathematics by the University of Glasgow in 1986 and a PhD by the University of Glasgow in 1989. He is a member of IA since 2017.

Current research interests focus on theoretical cosmology, in particular physics of the early universe including inflation, and the measurement and interpretation of cosmological parameters. He is a member of the Dark Energy Survey collaboration.
