Professor Kazuya Koyama is a leading scholar in theoretical cosmology at the University of Portsmouth's Institute of Cosmology and Gravitation (ICG), part of the Faculty of Technology. His research focuses on understanding the origin of cosmic structure and the late-time acceleration of the Universe, with a particular emphasis on modified gravity theories as alternatives to dark energy. He has held prestigious awards including the Philippe Leverhulme Prize (2009) and the Young Scientist Award from the Physical Society of Japan (2010). His work is funded by major grants like the ERC Consolidator Grant 'Cosmological Tests of Gravity' and previously the ERC Starting Grant 'Modified Gravity Models as an Alternative to Dark Energy'. Education: PhD in Theoretical Physics from Kyoto University (2002). Key collaborations include the Euclid space mission and joint projects with Kyoto University, recognized by the Daiwa-Adrian Prize (2010). His research integrates advanced numerical simulations (e.g., MGCAMB, COLA methods) and observational analysis for cosmological probes like the Euclid telescope and SDSS surveys. Key themes include testing general relativity on cosmological scales, emulating gravity models, and analyzing large-scale structure data. Research Interests: Structure formation, cosmic acceleration, modified gravity, dark energy, stochastic inflation, and cosmological parameter inference. Current projects emphasize Euclid mission preparations, nonlinear structure simulations, and constraining gravity theories using redshift-space distortions and weak lensing. Grants & Collaborations: ERC Consolidator Grant (2014–present), STFC support, Royal Society International Joint Project with Kyoto University. Active in international initiatives like the Novel Probes Project and Euclid Consortium, focusing on gravity tests and cosmological parameter estimation. Labs/Teams: Leads research groups at ICG on cosmological tests of gravity, large-scale structure analysis, and modified gravity simulations. Collaborates with global teams on Euclid mission data exploitation and N-body simulation development.
