Professor Zhang is a prominent scientist for his pioneering contribution in laser-plasma physics and high field physics. He is an Academician of Chinese Academy of Sciences (CAS), foreign associate of American National Academy of Sciences (NAS), member of Germany Academy of Sciences Leopoldina, Foreign member of Royal Academy of Engineering (FREng) and Fellow of the Third World Academy of Sciences (TWAS).
He received Ph.D. degree in 1988 from the Institute of Physics, Chinese Academy of Sciences (CAS). From 1989 to 1998, he first worked at Max-Planck-Institute for Quantenoptik in Germany, then the Rutherford Appleton Laboratory and Oxford University in the UK. He became the deputy Director of the Insitute of Physics, CAS in 1999 and then Director General of the Bureau of Basic Sciences, CAS in 2003. In 2006, he was appointed as the 39th President of Shanghai Jiao Tong University.
He works on laser-plasma physics and high energy density physics. He has made outstanding contributions to development of soft X-ray lasers, generation and propagation of hot electrons in laser plasmas in connection with inertial confinement fusion (ICF), and lab simulation of astrophysical processes with laser-produced plasmas. By clever design to enhance pumping efficiency, he and his collaborators demonstrated saturation of soft-X-ray laser output at wavelength close to the water window. He discovered through theory and experiment that highly directional, controllable, fast electron beams can be generated from intense laser plasmas in liquids and solids. Such electron beams are useful for ultrafast electron microscopic studies and other potential applications. Understanding of how hot electrons are generated and propagated in laser plasmas and how the resulting electron beams emit from a target surface and carry away laser excitation energy is also important for understanding of the fast ignition process in ICF. Zhang is one of the Chinese pioneers on simulating astrophysical processes by laser plasmas in labs. He and his Japanese and Korean collaborators used high-energy laser pulses to successfully create conditions resembling the vicinity of the black hole and model the loop-top X-ray source and reconnection overflow in solar flares. Since 2001, he has published 180 papers in international scientific journals.
His service to the professional community is truly outstanding and unusually distinguished. In the period of 2000-2006, he was in charge of a large scientific facility project of Chinese Spallation Neutron Source (CSNS), which became the largest scientific project in China with 1.6 billion RMB investment. In 1999, he initiated and chaired the organization committee of the CPS Fall Meeting (Chinese Physical Society), which has become the most important annual conference in Chinese physical community. Because of his great efforts, the CPS Fall Meeting has the greatest attraction to young physicists with greatly increased attendees from less than 150 in the first CPS Fall meeting in 1999 to over 1,700 attendees in the 14th CPS Fall meeting last year. He has been recognized by the Chinese science community as one of the natural leaders in the younger generation in China. He is editors of several national and international journals, such as "Optics Express", "High Energy Density Physics", "Chemical Physics Letters", "Journal of Physics B", "Plasma and Fusion Research", "Physics of Plasmas", "Plasma Physics and Controlled Fusion" etc. He served as the President of Association of Asia Pacific Physical Societies (AAPPS) in the period of 2008-2010.
Because of his academic achievements and professional services, Professor Zhang was elected the Foreign Associate of National Academy of Sciences (NAS) in 2012, the Foreign Member of Royal Academy of Engineering (FREng) in 2011, the Fellow of Third World Academy of Sciences (TWAS) in 2008, the member of the German Academy of Sciences Neopoldina, Academician of the Chinese Academy of Sciences in 2003. His research has been recognized by TWAS with the 2007 TWAS Prize in Physics; by the Chinese State Council with the State Natural Sciences Prize in 2006; by the Hong Kong Ho-Leung-Ho-Lee Foundation with the award of the Science and Technology Progress Award in 2006; by the Overseas Chinese Physical Society (USA) with the 2004 Achievement in Asia Award; by the Chinese Physical Society with the 2003 CPS Rao Yutai Award in Physics; by the Chinese Optical Society with the 2002 COS Wang Daheng Award in Optics; by the Hong Kong Qiushi Foundation with the Qiushi Award for Outstanding Young Scientists in 1999; by the State Council of China with the National Award for Outstanding Young Scientists in 1998.
