Established in 2017, the SPIE Mozi Award recognizes outstanding discoveries, inventions or scientific and technical achievements in the field of optics. It is named in honour of the Chinese philosopher, scientist and engineer, Mozi (468-391 BC), the first person in recorded history to mention the simple principles behind the concept of camera obscura.

Former recipients of the SPIE Mozi Award include Professor Yuri Kivshar (2020), Head of Nonlinear Physics Centre of the Australian National University (ANU); Sir John Brian Pendry (2019), Professor of theoretical solid state physics at Imperial College London; and Professor Din Ping Tsai (2018), Distinguished Professor at the National Taiwan University.

“I am deeply honoured to receive this award, which is recognition not only for myself but also for the team of collaborators and students whom I have worked with over the years. It is an encouragement which will keep us moving forward to achieve new milestones in research excellence.”, said Professor Zhang.
