Prof Hiranya Peiris
Room G20, Cosmoparticle Hub, KLB
Dept. Physics and Astronomy, UCL, Gower Street
  • Professor of Astrophysics
  • Dept of Physics & Astronomy
  • Faculty of Maths & Physical Sciences
I was an undergraduate at the University of Cambridge, where I gained an MSci. in Physics in 1998. I got my PhD in 2003 at the Department of Astrophysical Sciences, Princeton University, and subsequently, was a Hubble Fellow at the Kavli Institute for Cosmological Physics, University of Chicago. I returned to Cambridge in 2007, spending two years at the Institute of Astronomy, and moved to UCL in 2009. I am currently a Lecturer in Cosmology and STFC Advanced Fellow in the Astrophysics Group. I was born in Sri Lanka, a beautiful island in the Indian Ocean.

Research Summary
My primary research interests are in theoretical and observational cosmology, particularly focusing on the cosmic microwave background (CMB), the fossilized heat of the Big Bang. My recent research has involved using the Wilkinson Microwave Anisotropy Probe data to determine the basic characteristics of the Universe (its contents, history, expansion rate and eventual fate), and exploring the implications of the data for early universe physics. I am a core team member of the Planck Collaboration. Planck, an ESA satellite, is a next generation CMB mission which is currently mapping the CMB from the distant L2 Lagrange Point. I am very interested in observational signatures of physics beyond the standard model (string cosmology, inflation, dark energy etc). I also enjoy thinking about galaxy evolution, stellar dynamics and Galactic structure.
