Research Interests

My research fields include quasar surveys, statistical and machine learning methods in astronomy. My PhD thesis project was “Searching for Quasars behind the Galactic Plane”, aiming to select quasar candidates at |b| <= 20 deg with Machine Learning, and identify the candidates with optical telescopes. Currently, I am working in the OU-NIR and the Galaxy and AGN Evolution Science Working Group of the Euclid mission, focusing on NIR pipeline development and the quasar/AGN science in the Euclid survey.

  • A survey of quasars behind the Galactic plane: I have been working on the selection of quasar candidates at |b| <= 20 deg with Machine Learning, and the identification of the candidates with optical telescopes. The project has resulted in the discovery of a large number of new quasars behind the Galactic plane, which are important for the assessment of the systematic errors of astrometry of the Gaia mission.
  • Improved Gaia DR3 Quasar Candidate Catalogs (CatNorth and more): I have been working on the improvement of the Gaia DR3 quasar candidate catalog with Pan-STARRS1 and CatWISE, aiming to provide a more complete and reliable quasar sample for the community.

  • The LAMOST Quasar Survey: I have been working on the LAMOST quasar survey, aiming to provide a large and complete quasar sample for the community.

  • AGN/quasar science in the Euclid mission: I am working in the OU-NIR and the Galaxy and AGN Evolution Science Working Group of the Euclid mission, focusing on NIR pipeline development and the quasar/AGN science in the Euclid survey.
