Cortex & Cleats is my year-long neuroscience–athlete research project that produced a published Curiex paper, a policy presentation on youth concussion safety at SAS, and an ongoing effort to implement these measures across Singapore

Elite Concussion Testing 

Cutting-edge research

New brain imaging shows that repeated headers alter youth players’ white-matter integrity.
Labs now link ball speed, inflation and cervical strength to impact outcomes, and major bodies like FIFA are funding trials to translate the data into practical protections.

Policy in elite leagues

From February 2021 the Premier League allowed two “concussion substitutions” per team: if a player shows head-injury signs, they can be removed without using a normal sub

U.S. athletes

The United States Soccer Federation banned heading for players aged 10 and under and limited headers in practice for ages 11-13 to 15-20 per week. This has been linked to a ~26% drop in concussion risk

Biology specific risk

Studies show female youth players suffer higher concussion rates than males in equivalent soccer levels. For elite U.S. college women’s teams (D1-D3), managing heading exposure and neck-strength protocols is becoming standard to protect long-term brain health.

C&C Paper

A Policy and Neuroscience Review 

My research paper (linked) examined how repeated soccer headers affect the brain and how existing safety policies could be improved for young athletes.

 

I began by identifying a clear research question and gathering peer-reviewed studies from neuroscience, sports medicine, and biomechanics journals. I reviewed over twenty studies spanning neuroimaging, biomechanics, and epidemiology. This included work showing that even subconcussive headers can alter white matter structure (Lipton et al., 2013) and that female athletes experience greater brain strain due to weaker neck musculature and smaller head-to-ball mass ratios (Brooks et al., 2021). I also compared lab data on ball velocity and air pressure with field data identifying high-risk scenarios, such as defensive clearances and corner kicks, where impact forces are significantly higher.

Once I established the scientific foundation, I analyzed policy documents and position statements from FIFA, the Premier League, and U.S. Soccer to understand how research findings have been applied in practice.

 

I organized my paper around three main areas: the scientific evidence, current policy gaps, and realistic recommendations for youth and high school soccer. I got published in the 2025 December Volume of the Curieux Academic Journal (linked). Writing this paper required balancing technical accuracy with clarity, and the process helped me understand how data-driven research can shape safer athletic policies for future players.

C&C Policy 

A Policy Presentation

My policy proposal and presentation focused on turning research into a practical program for SAS. I started by drafting multiple policy versions, integrating scientific studies on concussion risk and biomechanics.

 

To make the policy realistic, I interviewed athletic trainer Tomo and coach Jason Adkison, learning how practices are run, which drills expose players to the most headers, and how athletes respond to new safety measures. Their insights helped me refine my proposal so it could actually be implemented without disrupting skill development.

I also reviewed the SAS concussion policy, which requires baseline testing for all athletes before the season. Building on that framework, I designed a preventative program centered on neck and upper-body strengthening. I chose this solution because research shows that stronger cervical and shoulder muscles absorb impact forces, reduce head acceleration during headers, and lower cumulative brain strain. Unlike simply banning headers, this approach empowers players to stay active and develop skills safely while protecting long-term brain health.
