Hiranya Peiris

Hiranya Peiris is Professor of Astrophysics at University College London and co-Director of the UCL Cosmoparticle Initiative. She is also Professor of Cosmoparticle Physics at Stockholm University. Her research aims to test fundamental physics using large cosmological datasets, including the cosmic microwave background and galaxy surveys, using an approach combining observations, theoretical physics, and advanced statistical methods. She completed her undergraduate studies at Cambridge University in 1998 and got her Ph.D. from Princeton University in 2003. She was a Hubble Fellow at the University of Chicago in 2004-2007 and then moved back to Cambridge as a Halliday Fellow of the Science & Technology Facilities Council. She began a faculty position at University College London in 2009. In 2016 she was elected fellow of the American Physical Society and vice president of the Royal Astronomical Society. She was also director of the Oskar Klein Centre for Cosmoparticle Physics in Stockholm from 2016-2022.

Peiris’s work has been recognised with awards including the Institute of Physics (IOP) Fred Hoyle Medal (2018), the Göran Gustafsson Prize in Physics of the Royal Swedish Academy of Sciences (2020), the Max Born Prize of the German Physical Society and the IOP (2021), and the Eddington Medal of the Royal Astronomical Society (2021). Her contributions to survey cosmology have been recognised through a share of the Gruber Cosmology Prize (2012) and the Breakthrough Prize in Fundamental Physics (2018), both awarded to the Wilkinson Microwave Anisotropy Probe (WMAP) Science Team. She was elected a member of the Royal Swedish Academy of Sciences in 2022.
