Chamkaur Ghag

Chamkaur Ghag graduated from Queen Mary University of London with an MSci in Physics in 2003 before moving to the University of Edinburgh to begin his PhD. His research focused on direct Dark Matter searches and developing low background instruments capable of recording extremely rare and faint signals from particle interactions. In particular, he worked on directional Time Projection Chambers (TPC) with gaseous targets and the construction and exploitation of the DRIFT-II Dark Matter experiment at Boulby Mine. In 2006 Chamkaur began work with the ZEPLIN-II and ZEPLIN-III experiments at Boulby, operating the early liquid xenon TPCs and pioneering this now leading technology in the search for dark matter. Chamkaur moved to UCLA in 2011where he worked on the XENON100 experiment at Gran Sasso before taking up a faculty position at UCL in 2012 where he started the dark matter group, joining the LUX dark matter search experiment based at SURF. Chamkaur Ghag is one of the founding members of the LUX-ZEPLIN (LZ) experiment that brings together the LUX and ZEPLIN programmes to deliver the most ambitious direct Dark Matter experiment yet. LZ is currently under construction and will begin operations in 2020. He co-leads the crucial Backgrounds and Screening Work Package that ensures the experiment meets its low-background construction requirements, and delivers the high-precision Background Model against which any potential signal will be evaluated. Low-background construction is achieved through the world-class infrastructure he has developed in the UK. This includes gamma-spectroscopy at Boulby, where Chamkaur is Principal Investigator of the Boulby Underground Germanium Suite (BUGS), and a new cutting-edge mass-spectrometry facility at UCL. Dr. Ghag presently leads development of a novel radon emanation facility at Rutherford Appleton Laboratory to complement this capability. In 2016 he was appointed Chair of the Dark Matter UK (DMUK) Consortium that brings together the UK’s Dark Matter researchers. Chamkaur was also made Chair of the STFC’s Particle Astrophysics Advisory Panel (PAAP) in 2016, having served as Deputy Chair since 2014. Other roles include membership of the Institute of Physics Astroparticle Physics Group and the STFC Boulby Science Advisory Group. His term with the EAC committee begins in the Spring of 2019.
