Sergey Sergeyev received his MSc and PhD degrees in optics and laser physics from Belarusian State University (BSU), Minsk, in 1985 and 1991, respectively. He has 34 years of academic experience and 3 years of industrial experience in the field of polarization spectroscopy, telecom, laser physics, and nonlinear fiber optics. He is now an Associate Professor at the Aston Institute of Photonic, Technologies (AIPT) at Aston University, UK. He has published over 200 journal and conference papers, 4 book chapters, and filed 7 patent applications. He has recently supervised of 6 EU and UK projects covering the polarization phenomena in spectroscopy, fiber optics, telecom, and laser physics. Chengbo Mou received his B.Eng. degree in electronic science and technologies (optoelectronics) from Tianjin University, China, in 2004, in addition to his M.Sc. degree in photonics and optoelectronic devices from the University of St Andrews, U.K., in 2005, and a Ph.D. degree in photonics from Aston University in 2012. He then worked as an Industrial Research Fellow with Aston University. In 2016, he joined in the Key Laboratory of Specialty Fiber Optics and Optical Access Networks at Shanghai University as a Full Professor. His research interests include nanophotonics, nanomaterial-based nonlinear photonic devices, ultrafast fiber lasers, novel type of mode locked lasers, and nonlinear applications of advanced fiber grating devices. He is the recipient of National High Level Oversea Recruitment programme of China, the Young Eastern Scholar Fellowship from the Shanghai Institute of Higher Learning. He has published over 100 journal and conference papers, 3 book chapters. He has been extensively involved in projects supported by Natural Science Foundation of China, Natural Science Foundation of Shanghai, Ministry of Education China, and MOST China.
