The Naval Medical Research Unit- Dayton’s (NAMRU-Dayton) Mission: To maximize warfighter performance and survivability through premier aerospace medical and environmental health research by delivering solutions to the Field, the Fleet and for the future.

NAMRU-Dayton is composed of two research directorates:


The Naval Aerospace Medical Research Laboratory conducts aerospace-relevant research in the biomedical and behavioral sciences. Our lab is equipped with capabilities in acceleration and sensory sciences, biomedical, and engineering and technical services, all of which are supported by a unique collection of state-of-the-science research devices. Our research portfolio enables NAMRU-Dayton to transition validated knowledge and effective technologies to the fleet, mitigating and preventing leading factors associated with aeromedical mishaps.

The Acceleration & Sensory Science Department addresses a number of aircrew issues including cognitive aspects of spatial disorientation prevention and mitigation. Recently this focus has shifted to implications of physiological episodes during flight. The department also studies Spine Biodynamics focusing on neck and low back pain in aviators and aircrew. Scientists focus on the biomechanical and physiological effects to deliver technologies for quantitative assessment of spine function and rehabilitation. This department is home to our vision science lab where a broad spectrum of basic and applied research are used to address problems associated with human visual performance, including laser veiling glare and laser eye protection as well as the impact of low level neurotoxins on aircrew. This team is responsible for the development and validation of new color-vision test and standards for aviation screening.

The Biomedical Science Department focuses on conducting cutting edge research and engineering technology development to directly address the human factors and human performance needs of the warfighter. The department’s core capabilities focus on the top human centered issues of aerospace mishaps, incidents and near misses. Our fatigue team focuses on fatigue measures and countermeasures using pharmacologic alertness aids in our fully equipped Fatigue Assessment and Countermeasures Lab. The altitude effects team looks at respiratory physiology, alternobaric affects, aircrew status monitoring, and mitigation. The Motion Sickness Countermeasures Laboratory tests pharmacokinetics and efficacy of low dose medications as a motion sickness countermeasure. This team also evaluates simulator sickness in mixed reality environments and the effects of active behavior vs. passive kinesis on motion sickness. Additionally, our scientists are involved in the development and validation of cognitive and personality measures in the selection of unmanned aircraft systems.

The Engineering and Technical Services Department is home to the Disorientation Research Device – the KrakenTM, which is a one-of-a-kind research platform capable of multi-axis motion for up to two subjects in yaw, pitch, roll, and heave while undergoing planetary and linear accelerations. A unique team of mechanical and electrical engineers, statisticians, software engineers and fabrication specialists support the operation of this device. The department supports the entire directorate in the maintenance of its core science devices and is home to a fabrication shop equipped for technicians to construct in-house research devices, reconfigure existing devices, and perform a wide range of fabrication in support of research requirements.

The Environmental Health Effects Laboratory uses unique and state-of-the-science technologies to assess the potential health risks associated with exposure to chemicals, environmental hazards and stressors and military settings, to include occupational and extreme operational environments. The lab is equipped with capabilities in occupational and environmental health; inhalation toxicology, and technical research support. Our scientists evaluate the effects of exposure from multiple standpoints. The ultimate objective is to develop health protective exposure standards for our military and civilian populations.

The Occupational and Environmental Health Department uses in vitro, in silico, and animal models to investigate environmental health effects relevant to the Navy and the Department of Defense. The research teams look at topics such as jet fuel and noise, toxicity of jet fuels, and in vitro lung and dermal screening tests for fuel toxicity. The department’s in vitro capabilities allow for a more cost effective and rapid screening of compounds and the eventual replacement of whole animal testing. Scientists in this department also use electrophysiology and behavioral testing to assess environmental exposure.

The Inhalation Toxicology Department uses various biological and chemical model systems to examine the toxicities of materials via various routes of exposure. The department’s inhalation capabilities are extensive, allowing for exposures to gases and vapors, aerosols, particulates, and nanoparticles. Whole-body and nose-only inhalation chambers are used allowing scientists to assess toxicities of chemicals and materials at the molecular, cellular, organ and whole body levels. Efforts have concentrated on desert sand and burn pit emissions, nanomaterials, and fire extinguishing materials. Scientists in this department also focus on submariner health and were instrumental in establishing the current exposure standards for atmospheric components. Additionally, toxic load modeling and inhalation at altitude studies aim to evaluate how altitude and oxygen contribute to hypoxia-like events.
