Diar Abdlkarim

Sensorimotor Neuroscientist & Research Leader

I study how the brain controls natural movement — through EEG, the science of touch, and motion capture — and build the research infrastructure, instruments and ventures that turn it into real-world technology. I also run hands-on courses teaching scientists motion capture and VR in Unity.

Growing minds, away from screens

A new research-led venture on how fine-motor and cognitive development intertwine in early childhood — and how technology can guide young children back toward rich, physical-world interaction during these critical developmental stages.

About

I build the science, the infrastructure, and the companies that turn how the brain controls movement into technology people can use.

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.

I established and lead the University's markerless Movement Lab, research infrastructure now used across research groups. Previously at Meta, I contributed to the markerless, scalable hand tracking now integral to the Quest product line and used by millions worldwide. As Co-Founder & Director of Motion Dynamics, I translate this science into hand-tracking hardware, haptics and XR software — and I teach it through courses for scientists.

Hand tracking, shipped to millions

At Meta I contributed to 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 interact with virtual worlds using nothing but their hands.

Leadership & impact

Building infrastructure, groups and ventures

The through-line of my work is independence: creating the facilities, collaborations and companies that let new science happen — and mentoring the people who deliver it.

Research infrastructure

Founded & lead the Movement Lab

I designed, specced and established a state-of-the-art markerless motion-capture facility now used across research groups at the University of Birmingham — a shared research asset I lead, and a magnet that draws collaborators and grant co-investigator roles into the department.

Supervision & independence

Opened a new research line in sign language

I opened a new direction applying kinematic assessment to sign-language acquisition, and I mentor the PhD researcher delivering it — reflected in our co-authored work. It shows an independent research agenda beyond my own hands-on projects.

Convening & income

Brokered a funded PhD studentship

I initiated a cross-college neuroscience × immersive-simulation collaboration — leveraging facilities no other group in the department has — and converted it into funded PhD capacity, bringing new research income and people into the group.

Impact, enterprise & training

From lab to real-world impact

Through Motion Dynamics, applied partnerships, the Kenilworth Revealed AR heritage project, and training courses for scientists, I take research out of the lab into products, skills and community — the basis of an impact and knowledge-exchange narrative.

Research

The neural control of natural action

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

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 markerless mocap and hand-tracking hardware, 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 use.
