Our research comprises a range of studies related to the sense of touch in various contexts being it clinically relevant like for example stroke, pain, diabetic neuropathy, loss of limb or solving engineering problems by borrowing ideas from biological systems to build dexterous robotic manipulators and prosthesis which can also feel.

Our research program is interdisciplinary and relies on��innovative platform capabilities linking the neurosciences, medicine and engineering disciplines.

• Neural code – the language of the nervous system; how to eavesdrop and understand neural communication and how to send our own messages through this channel

Touch receptors in the fingertips communicate with the brain using short electrical impulses also called spikes. My research is about how those impulses encode information and how it is interpreted by the brain. To address these questions we have learned to create those exact patterns of spikes in touch neurons using non-invasive mechanical stimuli. This technology is unique to our laboratory and has been developed over several years of tight collaboration between Dr Richard Vickery and me. We have gained unprecedented access to neural communication at the level of single neurons and the ability to investigate how spiking activity in those neurons influences perceptual experience. With this knowledge of neural code and non-invasive access to the communication channel we can “trick” the brain into thinking it is touching objects that are our artificial constructs.

• Dexterity of the human hand – how hand movements are controlled by sense of touch and how this knowledge could be used to build a robotic or bionic hands

The dexterity of the human hand still remains unmatched by the most advanced artificial devices - largely because it is not understood how relevant sensory information is extracted and utilised. My research builds upon interdisciplinary technologies integrating sensory and computational neuroscience and biomedical engineering. It is directed to gain understanding of the sophisticated sensory and motor control mechanisms underlying the unique human ability to manipulate objects and use tools. Extending beyond the fundamental scientific focus of understanding sense of touch, this research is aimed to inform the development of next generation sensory-controlled bionic systems and tele-sensory haptics devices including telesurgery robots.

• Stroke - distorted touch perception after stroke

Recovery of hand dexterity after stroke cannot be achieved in the absence of tactile sensory information, but the interpretation of this input requires that orderly somatotopic representation of hand’s skin has to be preserved. Unfortunately, this is not necessarily the case after substantial reorganization of neural connectivity following brain tissue damage due to stroke. This research is important as without tactile sensory information, functional use of the hand is hardly possible, even when motor system is intact. Rehabilitation efforts that do not address this can bring only limited improvements.
