I am interested in galaxy formation and evolution, which is very broad topic and I am focusing on

• == galaxy-halo connections ==
  • identifying galaxy groups and protoclusters in galaxy surveys;
  • connecting galaxies across cosmic time to infer their redshift evolution;
  • relating the star formation activities and chemical evolution of galaxies to their large-scale enviornment;
  • linking the growth history of galaxy stellar mass and their super-massive black holes to the assembly of their dark matter halos;
• == dark matter halos ==
  • relating the assembly histories of dark matter halos to their internal structures and external environments;
  • simulating the orbital and structrual evolution of dark matter subhalos;
• == galaxies ==
  • estimating the physical properties of galaxies from their observable properties;
