Opportunities for research funding from the US military do not stop at the nation’s borders. In keeping with the globalization of science, military programs like those sponsored by the US Air Force Office of Scientific Research (AFOSR), cast a wide net in selecting research projects—including materials science research—for funding and other support.

AFOSR’s international programs include its Asian Office of Aerospace Research and Development (AOARD), headquartered in Tokyo. Director Kenneth Caster says the office covers the entire Asia-Pacific region where all researchers at eligible academic or research institutions and who have an active registration with the US government may participate. Details on eligibility, he says, can be found at http://www.SAM.gov

AOARD is one of AFOSR’s three international offices, the others being the European Office of Aerospace Research and Development and the Southern Office of Aerospace Research and Development. There is no grant cycle, AFOSR says—proposals are accepted year-round through open Broad Agency Announcements available at http://www.grants.gov

Within AOARD, materials research is concentrated on two main topics. The first is structural materials as applied to load-bearing structures, particularly for air and space applications. Particular focus areas, AOARD says, include metals, ceramics, composites, and “compliant” or soft materials, as well as novel processing techniques.

The other topic is materials discovery and manufacturing science, including exploration of new materials systems and the use of autonomous experimentation for materials discovery and manufacturing optimization. Materials systems of particular interest currently are high-entropy alloys, magnetic materials, programmable materials, flexible electronics, materials for extreme environments, multifunctional materials, and nanoscale materials and structures.

There are several reasons to work with international researchers, including researchers in the Asia-Pacific region, Caster says. First, basic research is international with about 80% occurring outside of the United States. Also, AFOSR wants to leverage large, national, and regional governmental investments, in particular research areas such as nanosciences and nanomaterials. That includes access to specialized and unique instruments and test capabilities, he says, for example Australia’s cyclotron—the only one of its kind in the world. And finally, he says, there is the intrinsic value of collaborating with researchers and institutes with different perspectives but similar goals.

Specific to the US Air Force, Caster says, “the goal is to develop materials in order to advance air, space, and cyber [technologies] and to prevent technical surprise.”

The professional linkages forged by AFOSR program officers and between researchers and collaborators themselves fuel interest in—and grant applications for—the monies available, according to researchers who have received grant funding from AOARD.

Francesca Iacopi, a professor of electrical engineering at the University of Technology Sydney, says she learned about AOARD funding through a visit by Caster to her university. Caster, she says, gave a presentation about AOARD and AFOSR, including the possibility for funding research groups outside of the United States.

Iacopi says she had already been working with a colleague from the US Air Force Research Laboratory, John Boeckl, “who is nowadays one of my closest collaborators. We started working together organically, as we were both interested in graphene and silicon carbide, and had very complementary expertise which created a great synergy.”

“I have two projects with AOARD,” says grant recipient Dipankar Banerjee, honorary professor of organic chemistry at the Indian Institute of Science, Bangalore. He says his group aims to construct both “a quantitative and predictive understanding of the phenomena underlying the materials development and application effort with an emphasis on engineering materials, and especially titanium alloys.” He says the two projects seek an understanding of microstructure evolution in titanium alloys and resulting properties, and that the funding for both was obtained because of his interactions with the US Air Force Research Laboratory and AFOSR staff members.

“A former colleague of mine at the Max Planck Institute for Iron Research in Germany told me about this program,” says Pyuck-Pa Choi, associate professor of materials science and engineering at the Korea Advanced Institute of Science and Technology. “The program seemed to be a very good opportunity for me to acquire funding for fundamental research on high-temperature materials.”

Choi received a grant of $50,000 per year for three years for research on engineering alloys for structural applications, in particular high-temperature applications.

“I thought that a proposal to develop new cobalt-based superalloys for aerospace gas turbine applications would fit very well to my research portfolio as well as to the research interests of the US Air Force and AOARD,” Choi says.

AOARD grant sizes vary depending on the specific location, type of research (theoretical versus experimental), and project length. The median award size is $58,000 for 12 months. One type of award is a one-year seed grant for proof-of-concept studies; other types of grants are given for scientific workshops and conferences.

And AOARD stays in touch with the researchers they fund.

“I have regular contact with my program managers and also occasionally with other program managers for AFOSR—they are very professional people and they are all scientists—some civilian and some military,” Iacopi says. “They do not apply to AFOSR for funding of their own research, so their judgment is unbiased by competition.”

“The contact was extensive during the phase of project submission and the experience was excellent. I found the program officers very supportive,” Banerjee says.

Iacopi says she encourages colleagues seeking funding for fundamental research with potential for a good payoff to consider one of the international programs of AFOSR, including AOARD.

“AFOSR prides itself on having supported over 70 Nobel Prize [laureates], from all over the world, early in their careers—which is admirable as it is always riskier to support early career researchers,” Iacopi says.
