Research Interests

Galaxy Evolution

Astrophysics: Galaxies

The evolutions of the stellar population, metallicity, and abundance of dust in the Milky Way, in local galaxies, and in dusty galaxies in the high-redshift universe

Interstellar Medium

Astrophysics: Interstellar Medium

The chemical evolution of the Milky Way. The nature, origin, and evolution of the dust generating the observed interstellar extinction, diffuse IR emission, scattered sunlight, elemental depletions, and X-ray haloes in the MW. Reprocessing of dust in the ISM accretion and coagulation.

Supernovae and Supernova Remnants

Astrophysics: Supernovae & SNRs
