New venture · Seeking funding

Growing minds, away from screens

A new venture exploring how fine-motor and cognitive development intertwine in early childhood — and how AI can be designed to guide young children away from screens and back toward rich, physical-world interaction during these critical developmental stages.

About

A young academic-entrepreneur working at the seam between neuroscience and technology.

My research asks a deceptively simple question: how does the brain command the body to act in the real world? To answer it I combine EEG to read the neural signatures of movement, psychophysics of touch to probe how we sense contact and force, and motion capture to measure action with millimetre precision — closing the perception–action loop in extended reality.

Previously at Meta, I worked on the markerless, scalable hand-tracking that is now an integral part of the Quest product line — putting camera-based hand input into the hands of millions of users worldwide. Beyond the lab I build: as Co-Founder & Director of Motion Dynamics I translate that science into hand-tracking hardware, haptics and XR software, and I teach the next generation of scientists to do the same.

Hand tracking, shipped to millions

At Meta I helped develop markerless, scalable hand tracking — camera-based input that needs no gloves or controllers and holds up across real-world hands, lighting and motion. That technology is now integral to the Quest line, letting millions of people worldwide reach out and touch virtual worlds with nothing but their hands.

What I do

Three roles, one mission

Understanding the neural control of movement and touch — and putting that understanding to work.

Motor cortex — where action begins
Academia

Research Fellow

University of Birmingham

Leading experiments in sensorimotor neuroscience — using EEG, psychophysics and motion capture to reveal how the brain encodes, predicts and recalibrates natural hand actions.

Enterprise

Co-Founder & Director

Motion Dynamics

Building the instruments the science demands — advanced hand-tracking gloves, fingertip haptics and XR pipelines — and taking them from prototype to market through ICURe and company formation.

Education

Leader & Educator

Immersive & Neurotech

Teaching researchers to build and test immersive experiments — VR in Unity, motion capture, 3D printing — and leading community work such as Kenilworth Revealed, bringing University of Birmingham innovation into local heritage and outreach.

Research

The neural control of natural action

Four intertwined threads that run from the brain to the fingertip and back.

Hippocampus — learning & adaptation
01

Brain imaging with EEG

Reading the neural signatures of movement to understand how motor plans are formed, predicted and corrected while people act in naturalistic, real-world tasks.

02

The science of touch

Sensory-motor neuroscience of the sense of touch — how the hand senses contact, force and texture, and how tactile feedback shapes what we do next.

03

Motion capture & tracking

Capturing fine-grained sensorimotor signals with hand- and finger-tracking hardware and optical mocap, measuring action with the precision that experiments demand.

04

Immersive technologies

Building XR, HCI and human–robot interaction systems that close the perception–action loop in real time — for research, rehabilitation and collaboration.

Selected work

From neuron to prototype

Hardware, software and studies that turn sensorimotor science into things people can touch.

Cerebellum — coordination & craft

AR · Community & Heritage

Kenilworth Revealed

I lead this collaboration bringing University of Birmingham innovation to the community — our AR technology lets visitors and tourists step into Kenilworth's fascinating history through an immersive story, driving local engagement, tourism and the local economy.
