I mostly work on nebular and stellar astrophysics in nearby galaxies, focusing on the chemical abundance diagnostics of massive stars and the ionized gas. I am also helping to establish the relation between luminosity and velocity dispersion in star-forming regions as a cosmological standard candle. Other interests include extragalactic Cepheids, planetary nebulae and blue supergiant stars.
I have taught various courses, including Introductory Astronomy, Archaeoastronomy and Fundamentals of Astrophysics. Currently I am teaching the ASTR 320 course Astronomical Spectroscopy.
