 bstract:Approximately two in every thousand stars in the night sky exhibit
  significant brightness variations and are known as variable stars. The st
 udy of variable stars is a classical field of astrophysics that witnessed 
 numerous breakthroughs during the last century. Today\, with the advent of
  wide-field time-domain surveys\, variable-star research is entering a new
  era\, with the number of known variable stars reaching the tens of millio
 ns. In this talk\, I will introduce how large-scale astronomical data can 
 be used to identify periodic variable stars and explore how these stars ca
 n be systematically combined into a powerful cosmic yardstick for measurin
 g distances across the Universe.\nBiography:Xiaodian Chen is a researcher 
 at the National Astronomical Observatories\, Chinese Academy of Sciences (
 NAOC). He received his B.S. in Astronomy from Beijing Normal University in
  2011 and his Ph.D. in Astrophysics from Peking University in 2016. His re
 search interests include variable-star astrophysics\, cosmic distance meas
 urements\, and artificial intelligence in astronomy.\n\n \n \n\nhttps://
