Ofer Lahav FRAS FInstP is Perren Chair of Astronomy at University College London (UCL). His research area is observational Cosmology. He served as the Head of Astrophysics (UCL) 2004-2011, as Vice-Dean (Research) of UCL's Faculty of Mathematical and Physical Sciences 2011-2015, and as Vice-President of the Royal Astronomical Society 2010-2012. Lahav chairs the UK Consortiums of the Dark Energy Survey and the Dark Energy Spectroscopic Instrument (DESI), as well as the DES Advisory Board. He is a member of the Science and Technology Facilities Council (STFC) Science Board, and Co-Director of the STFC Centre for Doctoral Training in Data Intensive Science. From 2012 to 2018, Lahav held a European Research Council (ERC) Advanced Grant on "Testing the Dark Energy Paradigm" (TESTDE programme).

Education[edit]

Lahav studied Physics at Tel-Aviv University (BSc, 1980), Physics at Ben-Gurion University (MSc, 1985) and earned his Ph.D. (1988) in Astronomy[2] from the University of Cambridge, where he was later a Member of Staff at the Institute of Astronomy (1990-2003) and a Fellow of St Catharine's College, Cambridge.

Research[edit]

Lahav's research is focused on cosmological probes of Dark Matter and Dark Energy,[3][4][5][6][7][8] in particular large galaxy surveys.[9][10][11][12][13] As of 2019 Lahav has co-authored over 400[14] research articles in peer reviewed scientific journals, including 10 invited review articles and book chapters. Lahav is a Thomson ISI highly cited author,[15] h-factor 83. His past doctoral students include Chris Lintott.[1]
