Recently, Zhang Shougang, chief researcher of Time and Frequency Group of the National Time Service Center, was selected with honor in the "100 Talents Program" of Chinese Academy of Sciences as overseas outstanding talent upon the examination and approval of the leading group of the "100 Talents Program" of Chinese Academy of Sciences. 　

Returned to China after studying in France, Dr. Zhang Shougang has been engaged in the research on quantum frequency standard while studying for master’s degree. In China, he had taken part in the optical research on sextupole cesium atom beam of cesium atomic clock of time and frequency benchmark, the development of optical pumping atomic clock, the development of the 1st cold atomic fountain clock in China—a major project of the National Natural Science Foundation in succession independently or as the backbone. In 1997, he arrived at SYRTE laboratory (LPTF originally) of Paris Observatory, France for visit and study, and carried out a large number of experimental researches on cold atomic fountain clock and frequency control under the guidance of internationally renowned scholar, Prof. A. Clairon, in the field of quantum frequency standard. In the process of cooperation on the task, Dr. Zhang Shougang often got guidance and help from Nobel laureate, C.C. Tannoudji and professors such as renowned scientist, C. Salomon, J. Daliabard, etc. Dr. Zhang Shougang transformed and assessed independently the 1st cold cesium atomic fountain clock (France F01) with highest precision in the world, whose performance after transformation takes a leading position all over the world. Dr. Zhang Shougang participated as the backbone in the development and testing organized by ESA on Ramsey cavity of cold atomic clock (PHARAO) which is the world's most advanced at present and will be run in the international space station. While in the overseas, Dr. Zhang Shougang also participated in a number of experimental studies on the general theory of relativity, and the development of 87Sr optical clock of cesium atom of Paris Observatory. In 2004, he obtained PhD in quantum physics from French Curie University with honors (the highest evaluation for degree). Dr. Zhang Shougang published and delivered over 30 papers and reports of international conference, among which, over 10 pieces were indexed by SCI and EI and quoted nearly a hundred times.

Since went on duty in March this year, Dr. Zhang Shougang attracted 8 talents of different levels and established a scientific research team of reasonable structure with the substantial support of leaders in the center and relying on his own power of influence; laboratory transformation is in process orderly and satisfactory achievements have been made in striving for and undertaking important national scientific research task such as "973 Project".
