James Johnson is a CTAC postdoctoral fellow broadly interested in galaxy evolution and the origin of the elements. Most of his work is centered on applying theoretical models of galactic chemical evolution to spectroscopic elemental abundance measurements of resolved stars in the Milky Way and nearby dwarf galaxies. Lately, he is particularly interested in what can be learned from these comparisons regarding how different elements are made in stars. James also dedicates a portion of his time to developing astrophysical software tools for broader use by the community.
