Bachelor, Master and internship projects at the Atmospheric Physics of Exoplanets (APEx) department

APEx is a department at the Max Planck Institute for Astronomy, dedicated to the study of exoplanet atmospheres. There is a lot of interesting science to be done, so we welcome applications for doing an internship or a thesis with us! However, APEx is still growing, and the number of potential supervisors is limited. To help us consider project requests in a structured and fair manner, please follow our application process described below.

  • Eligibility
  1. Standard projects can only be offered to students who can come to MPIA in person, with their own funding (but also see point 5!).

  2. Preference is given to local students from Heidelberg University.

  3. The MPIA does not admit students to Bachelor or Masters degree courses: students must already be registered for a degree before contacting us to do their thesis. Please provide proof of enrolment if you want to apply for a thesis at APEx.

  4. Local bachelor students can receive credit points through the “Projektpraktikum Code WPProj” module (Projektpraktikum Code WPProject

  5. A limited amount of funding is available for summer internships for non-local students through MPIA's Summer Internship Program Please note that the webpage you are currently on explains how to apply for internships in the APEx department. MPIA's Summer Internship Program is not related to APEx internships. Please submit applications for MPIA's Summer Internship Program through the link above and not through the "Internships" link below, which is only for APEx internship applications.

  • Application process
    In the forms listed below, please fill in all required information, including CV and grade transcripts. Please note that we will only consider applications that include a CV and transcripts. As we only accept students who can come to the MPIA in person, please indicate that this is possible with your own funds if you are a student not currently living in Heidelberg. If you do not mention this, we will not be able to consider your application.
