Dr. Yan Sheng received her PhD degree in Optical Physics from the Institute of Physics, Chinese Academy of Science (Beijing, China) in 2007. After this she undertook a two-year postdoctoral position at Max-Planck Institute for Polymer Research (MPIP), Mainz, Germany. This period involved versatile research programs from fundamental physics of light-matter interaction to advanced nonlinear phtonic structures and devices. In March 2010, she joined Laser Physics Center as an Australian Postdoctoral Fellow (APD) to develop her expertise in nonlinear optics. Dr. Sheng currently is a Fellow (level C) and her research interests include nonlinear photonic crystals and femtosecond laser writing of nonlinear photonic structures.
