About

Sylvia Ekstöm is an Associate Professor at Université de Genève, Switzerland. Her research focuses on stellar evolution, particularly regarding massive stars and their interactions in complex systems. She has recently published works on topics such as the evolution of red supergiants, nebular emissions from massive stars, and the implications of atmospheric models in stellar evolution.
