Anthony is Director of the Kavli Institute for Cosmology, Cambridge, a role he has held since September 2021. Prior to this, he was its Deputy Director for five years and also a Deputy Director at the Institute of Astronomy for four years. He is a Professor of Cosmology and Astrophysics at the University of Cambridge and holds a joint faculty appointment between the Institute of Astronomy and the Department of Applied Mathematics and Theoretical Physics. He is also a Bye-Fellow at Queens' College.

Anthony obtained his PhD in 1998, and followed this with Research Fellowships from PPARC and the Royal Society before joining the faculty at the IoA and DAMTP in 2006. Anthony is a cosmologist and his research focuses on testing the cosmological model and the origin of cosmic structure with cosmological observations. A particular emphasis is the origin, interpretation, and measurement of cosmic microwave background (CMB) fluctuations imprinted in the early universe and also at later times through interactions with large-scale structure. He was a Core-Team member of the Planck High-Frequency Instrument and is a member of the Simons Observatory, LiteBIRD and CMB-S4 Collaborations. He has been a member of STFC’s Science Board since January 2026.

Ben is a particle theorist. He is primarily interested in interpreting data coming from the CERN experiments in terms of new particles and forces. Then he tries to rule such new particles and forces out with other data. If this doesn't work, he asks what theoretical framework do they come from and can this explain any mysteries? Physics has infected his other interests such as Quantum Selves Life Drawing and Physics Song Writing. You can read about his specific interests in this Aeon article.

Hiranya Peiris holds the Professorship of Astrophysics (1909) at the Institute of Astronomy, University of Cambridge. She is a member of the Kavli Institute for Cosmology, Cambridge, and a Professorial Fellow of Murray Edwards College, Cambridge.

After obtaining her undergraduate degree at Cambridge, Professor Peiris completed her PhD at Princeton. She was a Hubble Fellow at Chicago before returning to Cambridge as a STFC Halliday Fellow. She was then appointed to a lectureship (2009) and Professorship (2015) at UCL. She was Director of the Oskar Klein Centre in Stockholm (2016-2022) and Director of the UCL Cosmoparticle Initiative (2016-2023).

Professor Peiris conducts interdisciplinary research based on extracting fundamental physics from cosmological data. She has led analyses of cosmological survey data from multiple major international facilities, as well as making major contributions to theoretical cosmology and statistical astronomy. 

Her work has been recognised by awards such as the IOP Fred Hoyle Medal and Prize (2018), 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 WMAP Science Team. She was elected a member of the Royal Swedish Academy of Sciences in 2022.
