    CV

    Summary

    PhD student in Department of Physics at Vrije Universiteit Amsterdam. From 2002 to 2006, Ziyu studied his Bachelor program of physics at Nanjing University of Science and Technology, China. After that he worked as a network manager in MetLife, Inc in Nanjing, China. From 2008 to 2010, he followed a Master Program of experimental physics at Leiden University, where he did two of 8-month research projects. The first project was to design and to couple light into optical waveguides with 200 nm thickness. The second project was to produce and to align Gold Nanorods (typically 10 nm x 10 nm x 80 nm) in both electric and magnetic fields. From 2010 until now, Ziyu is doing his PhD research in Department of Physics at Vrije Univesiteit Amsterdam. His research project is a laboratory study of Rayleigh-Brillouin scattering in Air and other gases. This project is required and funded by European Space Agency (ESA) for its first satellite based LIDAR (Aeolus) project. Ziyu Gu has also reported the results of this project in three scientific journals and in several international conferences. Next to his research project, Ziyu has obtained his driving license in the Netherlands, followed a Dutch language course and obtained the Inburgerings diploma (A2 voor werk). Additionally, Ziyu has been granted a permanent residence by Dutch government, which permits him to live and work freely in the European Union.
