My research focuses on luminous and massive stars, whose mass exceeds ten solar masses at birth, and which collapse into neutron stars or black holes at death. I am interested in massive star feedback, in the physics of their stellar winds, and in massive binaries with compact companions. Massive stars are among the progenitors of supernovae, gamma-ray bursts, and gravitational wave sources. I strive to understand all aspects of massive star lives from their formation to their demise, as well as their cosmic influence.
In my work, I use the largest space and ground based telescopes observing across the electromagnetic spectrum, in order to shed new light on some of the most urgent questions in modern astrophysics. The resulting images are often strikingly beautiful, as illustrated by the examples below. Click on the images to read more information about these objects and their observations.
