Uniform and precise calibration plays an important role in the current and next-generation surveys. In this talk, I will discuss challenges and opportunities of 1)  photometric calibration of wide-field photometric surveys, 2) wavelength calibration of spectroscopic surveys, and 3) flux calibration of slitless spectroscopic surveys in the era of LAMOST and Gaia.

His main research interests include wide field surveys, Galactic sturcture, dust, binary stars, and emission line nebulae. He currently focuses on developping innovative techniques in calibrations and data analyses for surveys including LAMOST, Gaia, CSST, Mephisto, and JPAS, to make optimal measurements of stellar observables and properties, and further to reveal the stellar populations, structure and formation history of the Milky Way. He was awarded the NSFC Excellent Young Scientists Fund in 2022.
