Understanding Blast to Better Protect the Brain

Mar 6, 2026

Our Growing Research Effort to Reduce Blast‑Related Traumatic Brain Injury

Traumatic brain injury (TBI) remains one of the most complex and least understood threats facing today’s law enforcement officers and defense personnel. While decades of research have advanced our understanding of blunt and ballistic impacts, blast exposure presents a fundamentally different challenge—one driven by supersonic pressure waves, complex reflections in confined spaces, and biological mechanisms that are still actively being investigated. Recognizing both the urgency of the problem and the gaps that remain, we are beginning a focused research effort aimed at better understanding blast exposure and ultimately reducing the risk of blast‑related TBI.

Unlike blunt impacts, blast exposure involves a rapidly propagating pressure wave that travels through the body, interacting with tissues in ways that are difficult to measure and predict. Enclosed environments—hallways, stairwells, rooms, and vehicles—can dramatically amplify these effects due to wave reflections and pressure stacking. This matters directly to operators such as breachers and tactical teams, who must make split‑second decisions about where to stand, how to position themselves, and how to reduce cumulative exposure over time. Clear, actionable guidance grounded in physics and biology is still limited.

Modeling Blast to Inform Safer Decisions

One of the first steps in our effort is applying advanced computational modeling to better predict blast pressures in realistic environments. We are contributing blast simulation and modeling expertise to support the development of tools that can estimate pressure levels in enclosed spaces following detonation. The long‑term vision for this type of capability is straightforward but powerful: enabling users to understand where pressure levels may be highest, where they may be reduced, and how small changes in position or environment can meaningfully affect exposure. This work focuses on validating predictions through physics‑based simulations—an essential step toward reliable, decision‑support tools for real‑world use. While details of specific programs and partners will be shared as appropriate, this work represents an important early milestone in translating complex blast physics into practical insight.

Building the Foundation

In parallel, our team has begun internal blast‑focused modeling efforts to support ongoing research and visualization. These simulations allow us to explore how blast waves propagate, reflect, and interact with the human body, and they form the foundation for generating clear, intuitive visuals that can communicate risk and mitigation strategies. This internal work is already shaping how we think about blast‑related TBI and how it differs from other injury mechanisms. Just as importantly, it allows us to ask better questions—about exposure thresholds, repetition, and how protective systems might be optimized in the future.

A Collaborative Research Ecosystem

Addressing blast‑related TBI is far too complex for any single organization to solve alone. That’s why collaboration is central to our approach. Across the broader research community, our colleagues and partners are advancing complementary efforts, including the development of sophisticated brain models capable of predicting tissue‑level strain from external loading, and experimental platforms designed to reproduce controlled blast environments in the lab. These experimental systems—essentially large‑scale shock tubes—make it possible to pair high‑fidelity physical testing with computational models, creating a feedback loop between simulation and experiment. This combined approach—using both advanced modeling and physical experimentation—is widely recognized as essential for tackling the biological and mechanical complexity of blast injury. We are actively exploring opportunities to integrate these methods as our research progresses.

Looking Ahead

This is only the beginning. As our work continues, we expect to share more about the science of blast, the tools being developed, and the collaborations helping to push this field forward. Future updates may include deeper technical discussions, highlights of experimental testing, and spotlights on the researchers driving this work. Ultimately, our goal is clear: to help translate cutting‑edge research into knowledge and technologies that meaningfully reduce the risk of traumatic brain injury for those who operate in blast‑exposed environments.
