I am working on the evolution of dust in the early universe. Because dust grains absorb stellar light and re-emit it by thermal radiation, the existence of dust can play crucial roles in revealing the evolution of the universe from observations. So far I have determined the composition, size distribution, and amount of dust formed in primordial supernovae, as well as the destruction efficiency of dust in shocked hot gas.

Currently I am studying the chemical evolution of dust and its impact on the relevant observations.
