The University of Bern hosts many domains of astronomy, from solar physics, to exoplanets, and satellite observations. The successful candidate will work in the space weather group, which combines building astronomical instrumentation, machine learning, and researching the physics of the Sun and stars.

The Astronomical Institute operates the Zimmerwald Observatory with 5 telescopes from 20 cm to 1 m. The quality of images observed with telescopes is usually degraded by atmospheric turbulence. Special optical systems, known as adaptive optics (AO), can be used to counteract this image degradation. The goal of this PhD position is to help design and develop an AO system for our 80 cm telescope at the Zimmerwald Observatory, test it in the laboratory and on site, and subsequently carry out own observations. The scientific targets range from high-resolution imaging of satellites to other astronomical objects.

Requirements:
* We are looking for highly motivated candidates with (or obtaining soon) a MSc in physics, astronomy, or a related topic.
* A strong interest in experimental work is desired, particularly in astronomical instrumentation, telescopes, and optics.
* Knowledge of programming in Python and of Zemax would be beneficial.
* At least a basic knowledge of astronomy is required and knowledge of astronomical data analysis is beneficial.
* Strong verbal and written communication skills in English.
* Strong analytical abilities and problem solving/troubleshooting skills.
* Teamplayer who likes to work with other group members and students.

Appointment:
Starting as soon as possible, upon mutual agreement. Funding for maximally 4 years. Support for conferences and collaborations is available.
