Character experience

In 1985, Zhang Xiang obtained a bachelor's degree from the school of physics of Nanjing University, and then stayed in the university to study as a postgraduate. In 1988, he obtained a master's degree from the school of physics of Nanjing University.

In 1996, he received a doctorate in mechanical engineering from the University of California, Berkeley. Later, he joined Penn State University as an assistant professor (until 1999).

In 1999, he joined the Department of mechanical and aerospace engineering at UCLA as an associate professor (1999-2003) and a full-time professor (2003-2004).

In 2001, he served as director of the Department of Defense's Muri metamaterial Research Center (- 2006).

In 2003, he was director of the center for nanoscience and engineering at the National Science Foundation of the United States.

In 2004, he joined the Department of mechanical engineering and the Institute of Applied Science and technology at the University of California, Berkeley as associate professor (2004-2005), Professor (2005 -) ErnestS.Kuh Lectures (2009 professor -).

In 2007, he was a scientist and director of Materials Science Department of Lawrence Berkeley National Laboratory (2014-2016).

In 2010, he was elected to the National Academy of engineering.

In 2014, he won the Fitzroy medal. In the same year, it was supported by 10 million yuan of special support fund for innovation and Entrepreneurship of Anhui high-level scientific and technological talent team.

On December 7, 2015, he was elected as a foreign academician of the Chinese Academy of Sciences.

In December 2016, he won the a.c. Eringen medal award of the American Society of Engineering Sciences.

On December 15, 2017, the Council of the University of Hong Kong adopted a resolution to appoint Zhang Xiang to replace Ma feisen as the 16th president of the University of Hong Kong for a five-year term.

On July 17, 2018, Zhang Xiang officially became the president of HKU. He promised to establish a long-term and close cooperative relationship with a wide range of stakeholders of HKU, including HKU members, the government and the community.

Main achievements

Achievements in scientific research

In 2005, Zhang Xiang's research group developed the world's first super lens, demonstrating for the first time the imaging effect that breaks through the diffraction limit of light. In 2007, super lens research breakthrough was selected as the top 100 scientific and technological developments in the world.

In 2008, Zhang Xiang's research group successfully prepared the world's first three-dimensional material with optical negative refractive index, and was selected by time magazine as the top ten scientific and technological discoveries and top 50 annual inventions in 2008. He extended the negative refraction principle of light to acoustics, and realized the acoustic super structural materials and devices with negative elastic modulus for the first time. At the same time, he led the development of plasma lithography technology, and successfully etched nano electronic circuits.

In 2009, the world's first surface plasmon semiconductor laser was developed.

In 2011, the world's smallest ultra wideband high-speed light modulator was developed using single-layer graphene, and the super exciton interaction and giant binding energy in two-dimensional semiconductor materials were discovered through two-photon absorption.

As of 2015, Zhang Xiang has published more than 300 journal papers, including science, nature, Journal of the American Academy of Sciences and physics review express. He has delivered more than 280 keynote speeches, plenary meetings and invited speeches at international conferences and institutions. The following is a list of representative papers:
