He is a research professor at the Institute of Geochemistry of the Chinese Academy of Sciences.
He later studied nuclear physics and worked in a particle accelerator laboratory.
He later put forward a hypothesis on the formation of iron meteorites, an evolutionary model of the formation of the meteorites which fell at Jilin in 1976, and a theory of multi-stage cosmic ray radiation history.
[1] As an expert in geological research on underground nuclear tests and extraterrestrial materials, Ouyang was among the first to advocate not only the exploitation of lunar reserves of metals such as iron, but also the mining of lunar helium-3, an ideal fuel for nuclear fusion power plants.
[2] On November 12, 2008, upon China's publication of a comprehensive lunar surface map, Ouyang encouraged all three Asian nations then involved in lunar exploration (China, India and Japan) to increase co-operation in furthering humanity's understanding of the Moon.
