Publications and talks

Papers on massive stars, stellar rotation and 3D spectral synthesis, plus collaborations in interferometry.

My research brings together observations and computational modeling to understand massive O- and B-type stars. These stars often rotate so rapidly that their surfaces are no longer well described by the simple one-dimensional picture used in classical stellar models.

I develop three-dimensional models that capture their distorted shapes and temperature structure, and connect them directly to the spectra and interferometric observations we obtain.
