Are you inspired by their passion and determination? We are currently seeking a/an

University assistant predoctoral

Are you interested in fundamental questions in theoretical physics and in the mathematical structures underlying General Relativity & Cosmology? The Gravitational Physics Group at the Faculty of Physics of the University of Vienna invites applications for a PhD position in theoretical and mathematical gravitational physics. The doctoral project will focus on modern aspects of mathematical and numerical cosmology. The precise focus will be defined during the initial phase of the appointment in accordance with the aims of the position and the background of the successful candidate.

Your personal sphere of influence:

As a university assistant predoctoral, you will join the Gravitational Physics Group at the Faculty of Physics. The position is intended for a doctoral project in theoretical and mathematical gravitational physics, broadly within the area of mathematical and numerical cosmology.

Possible research directions include mathematical and numerical aspects of structure formation in cosmology. The concrete doctoral project will take into account the previous expertise, interests and strengths of the successful candidate.

The group offers a research environment for candidates who are interested in fundamental questions and who want to develop a strong and independent profile in theoretical physics. You will also benefit from the broader research environment of the Faculty of Physics and the Vienna Doctoral School in Physics, which connects PhD students across all areas of physics.

Your future tasks:

You actively participate in research, teaching & administration, which means:

• You will work on a doctoral project in theoretical and mathematical gravitational physics, broadly connected to mathematical and numerical cosmology.
• You will present your research plan to the faculty and complete a dissertation agreement within 12-18 months. This will be reviewed and adapted on an annual basis.

• Your Master’s thesis was in theoretical physics, mathematical physics or cosmology.
• You have a profound background in theoretical physics and mathematics.
• You have excellent grades in advanced theoretical and mathematical courses during your studies.
• You have a solid working knowledge of matter models in general realtivity, in particular Vlasov matter, and you are willing to deepen your expertise in the mathematical and numerical methods relevant for the dissertation project.
• You are able to read and work with advanced research literature independently.
• You have experience in scientific writing, for example through a Master’s thesis or comparable written research work.
• You have an excellent command of written and spoken English.
• You are motivated to work independently while also contributing constructively to a research group.
• Previous knowledge of the following area is desirable: theoretical cosmology.

What we offer:

Work-life balance: Our employees enjoy flexible working hours and can partially work remotely. 

Inspiring working atmosphere: You are a part of an international academic team in a healthy and fair working environment.

Good public transport connections: Your workplace is easily accessible by public transport.
