Dr. Dawei Tang is a Senior Research Fellow at the Centre for Precision Technologies (CPT), University of Huddersfield. His research interests primarily include surface characterization, optical instrumentation, in-process surface metrology, signal analysis, and metrology driven by nanophotonics.

Dr. Tang completed his B.Eng degree in Mechanical Engineering at the University of Science and Technology of China (USTC) in July 2008. He then pursued his M.Eng degree in Optical Engineering at the University of Chinese Academy of Sciences (UCAS), completing it in January 2011. During his master's studies, his research focused on optical system design, particularly infrared imaging systems and illumination systems. Following his master's degree, Dr. Tang worked as a Research Assistant at the Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP), Chinese Academy of Sciences, from March 2011 to March 2012. During this time, he contributed to research on surface metrology of precision mechanical workpieces and computer-aided assembly of high-precision optical systems.

In April 2012, Dr. Tang began his doctoral studies at the University of Huddersfield, where he was awarded a PhD in July 2016. His thesis, titled "Investigation of line-scan dispersive interferometry for inline surface metrology," was completed under the supervision of Professors Xiangqian (Jane) Jiang and Dr. Feng Gao at CPT, University of Huddersfield.
