45,000 students and 8,000 employees in teaching, research and administration, all working together to shape perspectives for the future – that is the University of Münster (WWU). Embedded in the vibrant atmosphere of Münster with its high standard of living, the University’s diverse research profile and attractive study programmes draw students and researchers throughout Germany and from around the world.

The Institute Applied Physics at the WWU is seeking to fill the position of a

Postdoctoral Research Associate
Wissenschaftliche*r Mitarbeiter*in
(salary level TV-L E 13, 100%)

at the earliest possible date. We are offering a fixed-term full-time position for 3 years. Full-time employees are required to teach 4 hours per week during the semester.

Your tasks:
The position involves undertaking fundamental theoretical and experimental as well as application-oriented scientific and technological research on nonlinear optics (second- up to seventh-order effects) of temporal and spatial four-wave mixing, e.g. for frequency and mode conversion, as well as nonlinear spectroscopy and imaging. The position is tied to working towards a Habilitation.

Our expectations:

  • A completed graduate degree and a doctorate in physics, photonic or electrical engineering, mathematics, computer science, or a comparable subject area is required, preferably followed by a postdoctoral stay abroad.
  • Proven knowledge and experience, as far as is possible, in, preferably, all of the following topics is required: generation and characterisation of ultrashort laser pulses, experimental and theoretical nonlinear optics, and numerical modelling of the propagation of ultrashort laser pulses in scattering or structured nonlinear media.
  • An exceptional willingness to perform and outstanding skills in relation to working independently, problem-solving and presenting results is required.
  • A strong research profile in the relevant areas and ideas for innovative applications for third-party funding is expected.
  • Experience in project management, technical guidance, management of employees and raising third-party funding is an advantage.
  • Furthermore, fluency in spoken and written English is required, as is the willingness to acquire German in a timely fashion in order to commence teaching in the bachelor's program.

Candidates are expected to show the potential for building-up their own research sub-group within the Chair of Applied Physics that will incorporate independent research, project applications to relevant funding institutions within national and international frameworks, teaching and supervision of undergraduate and graduate students and the development of new courses. They should have already demonstrated the capacity to execute the proposed research and publish the accompanying results in respected journals. In order to widen the access to specifically processed photonic integrated circuits for the expected research activities the existing scientific collaborations with academic and industrial partners as well as additional activities in the Nanofabrication Centre of the University of Münster are strongly recommended.

Advantages for you:

  • integration into a supportive team in the interdisciplinary research field of modern nonlinear optics and laser physics
  • extensive modern laboratory equipment and access to high-performance grid and parallel computing as well as nanofabrication facilities
  • close cooperation with national and international partners from academia and industry
  • a stimulating environment with a high degree of independence and long-term prospects
  • the opportunity for a further academic qualification by working towards a Habilitation during the period of employment
  • in case of a fruitful collaboration, i.e. if all corresponding milestones are successfully completed, it will be possible to apply for a permanent position from mid-2025
  • a wide range of extracurricular education and sports offered by the university as well as a livable city located in the German-Dutch border region

The University of Münster strongly supports equal opportunity and diversity. We welcome all applicants regardless of sex, nationality, ethnic or social background, religion or worldview, disability, age, sexual orientation or gender identity. We are committed to creating family-friendly working conditions. Part-time options are generally available.

The University of Münster is an equal opportunity employer and is committed to increasing the proportion of women academics. Consequently, we actively encourage applications by women. Female candidates with equivalent qualifications and academic achievements will be preferentially considered within the framework of the legal possibilities.
