- Education and Previous Roles
Ofer studied at Tel-Aviv University (BSc, 1980), at Ben-Gurion University (MSc, 1985; supervised by Jacob Bekenstein) and earned his PhD from the University of Cambridge (1988; supervised by George Efstathiou and Donald Lynden-Bell), where he was later a Member of Staff at the Institute of Astronomy (1990-2003) and a Fellow of St Catharine's College.
At UCL he previously served as Head of Astrophysics (2004-2011), establishing Cosmology as a research area, and as Vice-Dean (for Research) of the Faculty of Mathematical and Physical Sciences (2011-2015).
- Research and Publications
- Cosmological probes of Dark Matter and Dark Energy
- Large spectroscopic and photometric redshift surveys
- Neutrino Cosmology
- Formation and evolution of galaxies
- Data Science
During 2012-2018 he held a European Research Council (ERC) Advanced Grant on "Testing the Dark Energy Paradigm" (TESTDE).
Ofer has over 400 research articles in refereed journals, see full publication list.
