Dr. David Stepp, Director

The Engineering Sciences Directorate serves as the Army's principal linkage with and conduit to the extramural research community in the following disciplines: materials science, environmental sciences, mechanical sciences, and electronics. Its mission is to promote, resource, and manage extramural basic research to produce scientific advances that create new, revolutionary warfighting capabilities; and to identify, resource, and manage basic research that provides innovative solutions and technological improvements for the current force.

Mechanical Sciences

Advances the Army and Nation's knowledge and understanding of the fundamental properties, principles, and processes involved in fluid flow, solid mechanics, chemical reacting flows, explosives and propellants, and the dynamics of complex systems of relevance to the Army and the DoD.

  • Solid Mechanics
  • Complex Dynamics and Systems
  • Propulsion and Energetics
  • Fluid Dynamics


Seeks materials and novel structures providing new pathways for the design and fabrication of electronic devices with properties that cannot be realized with current technology.

  • Biotronicss
  • Optoelectronics
  • Electronic Sensing
  • Solid State and Electromagnetics

Materials Science

Seeks to understand the fundamental relationships that link chemical composition, microstructure, and processing history with resultant material properties and behavior.

  • Materials Design
  • Mechanical Behavior of Materials
  • Physical Properties of Materials
  • Synthesis and Processing of Materials
  • Innovations in Materials (International Program)

Earth Sciences

The Earth Sciences Division of the ARO seeks to advance understanding of the terrestrial environment for the U.S. Army with special emphasis on Earth Materials and Processes and Environmental Chemistry. Research supported by the Division seeks to explore the properties of Earth materials and chemical species to discover how they interact with their environments and respond to external forces.
