Aaron Sigut, Professor and Graduate Chair

My main research interests are circumstellar disks around hot stars, classical Be stars, Herbig Ae/Be stars, and non-LTE radiative transfer as applied to precise stellar abundance determinations.  I am also interested in optical and near-IR stellar interferometry.   All of my research projects involve large scale computational modelling.
