The goal of my work is to understand the formation and evolution of cosmic dust, particularly where it is formed. Cosmic dust is a nuisance to astronomers as it blocks out optical light, affecting our view of the Universe. It is also very important as dust affects star formation, stellar mass loss rates, the formation of molecular hydrogen and planets. Recent work hints that the explosions of massives stars (supernovae) may produce a lot more dust than previously thought. This is especially important in the early Universe where fast-lived, massive stars would be the only source of dust.
