About

Zheng Cai is a leading figure in the design and development of next-generation astronomical instrumentation, with a focus on wide-field, highly-multiplexed spectroscopic surveys. His work is central to advancing large-scale structure cosmology, particularly through the MUltiplexed Survey Telescope (MUST), a pioneering 6.5-meter telescope capable of observing over 20,000 targets simultaneously across a ~5 square-degree field of view. Cai's contributions include leading the instrument trade study for the Wide Field Optical Spectrometer (WFOS) on the Thirty Meter Telescope (TMT), a first-light instrument delivering R~5,000 resolution across a broad wavelength range. His white papers on MUST outline its potential to conduct the first Stage-V spectroscopic surveys, revolutionizing our understanding of cosmic evolution. With over 14 citations across his most prominent works, Cai’s impact is evident in shaping the observational strategies that will define cosmology in the 2030s. His leadership in transitioning from large telescopes to dedicated survey facilities marks a transformative shift in astronomical research.
