Preventing Spread of an Avian Influenza Strain as an Army Veterinarian
Most people immediately assume someone working in the US Army does combat or engineering, but there are a vast and unique set of science skills among those who serve.

While studying outbreaks of H5N1 in Egypt in the mid-2000s, he also looked at the possibility of the virus spreading through migratory birds in global flyways.
