Dust Extinction
Color-magnitude diagrams (CMDs) of reddened stars can provide rich
information about dust extinction properties of nearby galaxies. I use CMDs
to study dust extinction as a way to constrain dust grain properties. My
research has made use of Hubble Space Telescope observations of resolved
stars in the SMC to understand how the dust extinction curve at
low-metallicity may be different from that in evolved galaxies.
