Dr. Marie Korsaga holds a PhD in Astrophysics and Cosmology from the Laboratoire d’Astrophysique de Marseille (LAM) in France and the University of Cape Town in South Africa. Her doctoral research explored the distribution of baryonic and dark matter in nearby galaxies, using state-of-the-art multi-wavelength spectral and photometric data – including infrared, optical, and HI observations.

She has lectured at Université Joseph Ki-Zerbo in Burkina Faso and conducted postdoctoral research at the Observatoire Astronomique de Strasbourg (ObAS) and the Instituto de Astrofisica de Canarias (IAC), focusing on the dynamics of galaxies through infrared and radio observations. 

She joined the Instituto de Astrofísica de Andalucía (IAA-CSIC) in September 2025 as a postdoctoral researcher with Lourdes Verdes-Montenegro, where she investigates the mass distribution of galaxies, particularly the role of dark matter in isolated and high-redshift galaxies, using deep HI observations from the MeerKAT telescope.

Beyond her academic work, Dr. Korsaga is deeply committed to advancing gender equity in science. She has been actively involved in initiatives promoting women in STEM, especially in developing countries. She also served as a fellow at the IAU Office of Astronomy for Development (OAD) in 2020, where she examined how the science community – and the astronomy community in particular – could contribute to global challenges, including the COVID-19 pandemic. Her reflections on this work have been published in blog articles featured on the IAU-OAD’s official website.

In recognition of her scientific achievements and outreach efforts, Dr. Korsaga received the inaugural African Women in Astronomy Early Career Award, granted by the African Network of Women in Astronomy (AfNWA) in collaboration with the International Science Programme of Uppsala University.
