Research
The focus of research in the lab is the interface between technology, engineering, and perceptual psychology. A specific emphasis of our research is virtual reality and haptic robotics. Work in the lab shows the close interplay between core understanding of sensory perception and the solutions to critical applied real-world problems.
One of the primary research areas in the lab utlises a custom built bimanual virtual reality and haptic robotic system that we call "The Matrix" Click here to find out more.
The lab extensively collaborates with external industry partners such as RACE (Remote Applications in Challenging Environments, part of the UK Atomic Energy Authority), Generic Robotics, Meta (Facebook Reality Labs), European Space Agency Rosetta Team, and Christie Hospital Manchester (NHS).
Below you will find a list of publications from the lab. You can also visit my Google Scholar profile.
