David has worked in academic VR research for over 20 years and is currently a Senior Research Fellow in the Virtual Environments and Computer Graphics group at University College London. He collaborates on a wide range of research and experimental work, with particular interest in how knowledge of human perceptual mechanisms can be exploited to overcome technical limitations of VR systems. This is manifested by studies spanning psychophysics, navigation control, interaction, haptics and social response within VEs, and he has published widely across these themes. David also runs UCL's Immersive VR Lab spaces, maintaining and overseeing a 4-wall CAVE-hybrid setup, mocap systems, haptics and telerobotic setups, and an ever-growing collection of VR and AR headsets.
