Hiranya Peiris

Hiranya V. Peiris is a British astrophysicist at University College London,[1] best known for her work on the cosmic microwave background radiation. She was one of 27 scientists who received the Breakthrough Prize in Fundamental Physics in 2018 for their "detailed maps of the early universe."

Education

Peiris was born in Sri Lanka. She completed the Natural Sciences Tripos at University of Cambridge in 1998,[2] at New Hall, Cambridge.[3][4] She earned a PhD at Princeton University from the department of astrophysical Sciences, where she first worked on the Wilkinson Microwave Anisotropy Probe (WMAP).[5][6]

Research and career

After her PhD, she went on to work at the Kavli Institute for Cosmological Physics at the University of Chicago as a Hubble fellow.[5] Having held several competitive postdoctoral fellowships,[7] in 2007 Peiris returned to the University of Cambridge as an Science and Technology Facilities Council (STFC) advanced fellow and was awarded a junior research fellowship at King's College, Cambridge in 2008. In 2009, Peiris won a Leverhulme Trust award for cosmology and secured a faculty position at University College London.[8]

She is currently Professor of Astrophysics at UCL[9] and also the Director of the Oskar Klein Centre for Cosmoparticle Physics in Stockholm.[10]

In 2012, the WMAP team (including Peiris) won the Gruber Cosmology Prize for their "exquisite measurements of anisotropies in the relic radiation from the Big Bang---the Cosmic Microwave Background".[11] WMAP's results on cosmic inflation, which Peiris contributed to, were described by Stephen Hawking as "the most exciting development in physics during his career".[12]

She was skeptical about the 2014 announcement of the discovery of primordial gravitational waves in the cosmic microwave background: "If they announce gravitational waves on Monday then I will need a great deal of convincing. But if they do have a robust detection ... Jesus wow! I'll be taking next week off." Mike Hockney used this quote to illustrate that even top scientists need convincing because scientific discoveries are always just interpretations of results.[13] Her skepticism proved well-founded: on January 30, 2015, a joint analysis of BICEP2 and Planck data was published and the European Space Agency announced that the signal can be entirely attributed to dust in the Milky Way,[14] though (non-primordial) gravitational waves have since been detected by different experiments.

In 2016, Peiris was elected a fellow of the American Physical Society and served as vice president of the Royal Astronomical Society.

In 2018, Peiris was awarded the Hoyle Medal and Prize of the UK Institute of Physics for “her leading contributions to understanding the origin and evolution of cosmic structure."[15]

In 2020 Peiris was awarded the Göran Gustafsson Prize in physics by the Göran Gustafsson Foundation and the Royal Swedish Academy of Sciences "for her innovative research on the dynamics of the early universe, which links cosmological observations to basic physics”. [16] She was also elected as a member of STFC Council, the senior strategic advisory body of the research council that funds particle physics and astronomy in the United Kingdom. [17]

Public engagement

Alongside academic talks, Peiris gives public lectures about cosmology.[18][19] She has written articles and given interviews for both radio and print media.[20] She has appeared on podcasts, television programs and the national news.[21] In 2013 she gave a talk at TEDxCERN, "Multiplying Dimensions."[22] That year she was selected as one of Astronomy's top ten rising stars by Astronomy Magazine.[23]

In 2014, the pseudonymously-written Ephraim Hardcastle diary column in the Daily Mail claimed that Peiris (along with Maggie Aderin-Pocock) had been selected to discuss results from the Background Imaging of Cosmic Extragalactic Polarization 2 (BICEP-2) experiment on BBC Newsnight because of her gender and ethnicity. These comments were condemned by mainstream media, the Royal Astronomical Society and Peiris' employer, University College London,[24][25][26] and the Daily Mail and its column backed down within days.[24][25] Peiris offered a rebuttal, "Groundbreaking science is blind to prejudice" in Times Higher Education.[27]

In 2017, Peiris collaborated with artist Penelope Rose Cowley to create artwork entitled "Cosmoparticle".[28]

Awards and honours

Peiris was a member of the 27-person team awarded the 2018 Breakthrough Prize in Fundamental Physics.[29] The US$3 million award was given for the detailed maps of the early universe generated from WMAP.[30] WMAP is a NASA explorer mission that was launched in 2001, which has transformed modern cosmology.[31][32] Other prizes include:
