My research field is stellar physics. Since 1996 I have been working in the field of photometry of pulsating variable stars of various types such as delta Scuti, SX Phoenicis, gammar Doradus, Subdwarf B, white dwarf, etc. In collaborating with several observational astrophysicists and groups from Spain, France, America etc., I have done a lots of photometry campaigns for the purpose of applying asteroseismic tools to probe the interior of stars.  I even played a crucial role in detecting a Neptune-like extra-solar planet, which is identified through gravitational micro-lensing technique for the first time in the world. My interests actually are extended to be the observational studies of various kinds of short-time scale variability in stars.  As of the end of year 2008, I have published 79 papers in international journals including MNRAS, AJ, A&A etc., of which 17 ‘SCI- papers’ were written by me as the first author, three of them are excellent papers recognized by our institute. My publication has been cited by other authors for more than 530 times, and the citation ‘SCI-papers’  without me in authors list amounted to 189 by that time. Several works were cited by the famous annual review, Astrophysics in 1999, 2000 & 2004, PASP.  In 2008, I was assigned to be the vice chief of the National Astronomical Observatories – Guizhou University Center for Astronomy, and began to take an accociate position in the National Big Science Project FAST’s administration office.
