From 65438 to 0946, he went to the United States and served as a researcher at Princeton Institute of Mathematics and a professor at Princeton University and the University of Illinois. 1950 March 16, returned to Beijing from the United States.
Hua has served as Professor Tsinghua University, Director and Honorary Director of Institute of Mathematics and Institute of Applied Mathematics of China Academy of Sciences, Chairman and Honorary Chairman of Chinese Mathematical Society, Director of National Mathematical Competition Committee, Academician of American National Academy of Sciences, Academician of Third World Academy of Sciences, Academician of Bavarian Academy of Sciences of the Federal Republic of Germany, Deputy Director and Vice President of Physics Department, Member of the Presidium of China Academy of Mathematics and Chemistry, Director and Vice President of Mathematics Department of China University of Science and Technology, Vice President of China Association for Science and Technology, and member of the State Council Academic Degrees Committee.
Hua is a member of the first to sixth the NPC Standing Committee and vice chairman of the sixth China People's Political Consultative Conference. He was awarded an honorary doctorate by Nancy University in France, The Chinese University of Hong Kong and the University of Illinois in the United States. Mainly engaged in the research and teaching of analytic number theory, matrix geometry, typical groups, automorphic function theory, multiple complex variable function theory, partial differential equations, high-dimensional numerical integration and other fields, and has made outstanding achievements. In the 1940s, the historical problem of Gaussian complete trigonometric sum estimation was solved, and the best error order estimation was obtained (this result is widely used in number theory). The results of G.H. Hardy and J.E. Littlewood on the Welling problem and E. Wright on the Tully problem have been greatly improved and are still the best records.
