About me

I am currently a Research Fellow at the European Space Agency (ESA) based at the European Space Astronomy Centre (ESAC) near Madrid, Spain.

Camille Diez

I was previously a doctoral candidate at the Institut für Astronomie und Astrophysik (IAAT) in Tübingen, Germany, where I obtained my PhD degree in astrophysics in May 2023.


Before that, I was a trainee at the Institut de Recherche en Astrophysique et Planétologie (IRAP) in Toulouse, France. I completed my master degree in astrophysics (2019) at the Université Toulouse III - Paul Sabatier also in Toulouse, France.

My research interests are focused on the multi-wavelength study of accreting neutron stars in binary systems and their local environment. I am also deeply engaged in promoting women in science and making astrophysics accessible through my outreach efforts.

Stellar winds in HMXBs

I study stellar winds in High-Mass X-ray Binaries (HMXBs), binary systems consisting of a compact object (neutron star or black hole) with a giant companion star.

Even though I have a strong affinity for fundamental research, I'm also equally passionate about taking part in outreach activities such as advocating for the recognition of women in science and sharing the marvels of science with a non-scientific audience or with students, both through public talks and teaching. Whether it's presenting at scientific conferences as part of my job or just indulging my enthusiasm, I love learning, communicating and sharing knowledge, in English or French.

Public speaker

I am regularly invited as a speaker for round tables for astro/scientific events such as Chercheuses d'étoiles organised by UPS in Space or for the Rencontres Tranfrontalières d'Astronomes Amateurs organised by SAPCB to share my experience as a young researcher.

Women in astrophysics

The recognition of women in science is deeply meaningful to me. I raise awareness at my own scale taking advice from inspiring women, such as Jocelyn Bell. I am also a member of the EDI (Equity Diversity Inclusion) office at ESA which aims at putting in place changes to overcome gender barriers that are still strongly implemented in scientific fields.

Scientific outreach

I particularly appreciate giving public talks which are efficient ways to convey accessible astrophysics to non-scientists. I was recently interviewed for a scientific documentary on black holes named Les mystères des trous noirs by the French YouTuber Zebroloss, official representative of the Francophone countries in the ESA’s influencer programme.
