The Trottier Institute for Research on Exoplanets (iREx), affiliated with the Department Physics of the Université de Montréal (UdeM), offers the Trottier Postdoctoral Fellowship each year in experimental, observational or theoretical astrophysics applied to the study of exoplanets, which enables forefront independent research related to exoplanets.

This fellowship is named in honour of the Trottier Family Foundation, which supports this fellowship as well as a large portion of our Institute’s research and education activities.

About the iREx

The iREx consists of a growing team of about 60 people working on a variety of observational, theoretical and instrumental projects related to the study of exoplanets and other related fields of astrophysics. They work within several research institutions located in Quebec, Canada (Université de Montréal, McGill University, Bishop’s University, Rio Tinto Alcan Planetarium of Space for Life, Université Laval). Our professors, researchers, and students are actively involved in large international projects related to the detection and characterisation of exoplanets, notably the James Webb Space Telescope, the SPIRou and NIRPS spectrographs, and have privileged access to time and data from these instruments. More information on iREx’s research programs can be found here:

The iREx has also a vibrant science education and outreach program led by astrophysicists who are seasoned science communicators. We believe in the importance of training scientists who have exceptional scientific research skills, but also outstanding communication skills. All of our members are involved in bringing science to a wide audience in a variety of ways.

The iREx advocates for diversity, inclusion and employment equity. We strongly encourage applications from women, visible and ethnic minorities, Indigenous people, persons with disabilities and people of all sexual orientations and gender identities to apply. With the support of our EDI committee, we are committed to the professional integration of people from groups that are traditionally under-represented in the physics research community.
