Geraint Ellis Rees is a British scientist who is Vice-Provost of research, innovation & global engagement[3] at University College London (UCL).

[11] He completed his PhD under the supervision of Chris Frith at University College London's Functional Imaging Laboratory in 1999.

His Who's Who entry lists his recreation as 'achieving a better work/life balance'[11] Rees research interests[17][18][19][20] are on the neural mechanisms underlying human consciousness in health and disease.

Most research involves functional MRI at high field, in combination with behavioral studies, transcranial magnetic stimulation and EEG/MEG.

A major focus of this work is therefore in studying interactions between visual cortex and these areas, both in the context of attention, and with respect to eye movements.

He co-edited a large reference book entitled the Neurobiology of Attention[24] with Laurent Itti and John Tsotsos, and is the author of numerous articles and invited reviews on the functional imaging of consciousness.

He was a member of the board of the Association for the Scientific Study of Consciousness until stepping down in 2007, and with Patrick Wilken organised its tenth annual meeting that was held at St. Anne's College, Oxford in June 2006.

[29] Rees was Chair of the Knowledge Transfer and Enterprise Board,[30] of the UCL School of Life and Medical Sciences between 2014-2017.
