Postdoctoral Researcher (f/m/d, Nr. 461-26)
salary group 13 TV-L (gross 59.324–84.319€)

The Emmy Noether Junior Group led by Dr. Brandt Gaches at the University of Duisburg-Essen is looking to hire a postdoctoral researcher to investigate the microphysics and chemistry of cosmic-ray interactions with icy dust grains. The group focuses on high-energy astrochemical processes, in particular the interaction of cosmic rays with dense molecular gas. The group uses a range of methods, in particular chemical modelling and theory. The group also leads the Astrochemistry Low-energy electron Cross-Section database.

The position is funded through the DFG-funded Emmy Noether group "Towards the next generation in cosmic-ray astrochemistry", hosted at the University of Duisburg-Essen.

Start of employment

2027-03-01

Duration of employment

2 years

Working time

39 h 50 min (100 %, part-time employment is possible)

Your main tasks

As the postdoctoral researcher on this project, you will help build an atomic-scale understanding of the interaction of energetic particle irradiation with icy dust grains. Your work will include:

• calculating the energy deposition and electron distribution in icy mantles following particle irradiation
• using ab initio molecular dynamics simulations to quantitatively investigate chemistry immediately after particle irradiation
• characterising the chemical structure of the simulated irradiated ices and the composition of the desorbed gas-phase molecules
• perform a broad parameter study for different radiation particle types, ice mantle compositions, and ice thicknesses

The results of this research will lead to a significant increase in our understanding of the buildup of complex organic molecules via cosmic-ray irradiation.

Your profile

• Must hold a PhD in astrophysics, physics, chemistry, or a relevant field by the start of the position
• Proficient knowledge of astrochemistry
• Excellent command of written and spoken English
• Proficient in C/C++ and/or Fortran
• Preferred: Experience in quantum chemistry methods, in particular ab initio molecular dynamics
• Preferred: Experience with the Geant4 physics package, or similar
• Preferred: A high degree of independence, self-initiative and creativity

We offer you

• a position in the public sector with reliable working conditions in a varied, multifaceted field of work and in a research-intensive environment
• an interesting, meaningful role with significant scope for creativity
• an appealing work environment characterized by respectful and appreciative collaboration
• a diverse range of continuing education and professional development opportunities
• various canteens and cafés run by the Studierendenwerk on our campuses
• attractive discounts through Corporate Benefits
• a family-friendly university culture (e.g., childcare options, counselling for family caregiving responsibilities, etc.)
• a prime location and infrastructure with excellent public transportation access and free parking
• flexible working hours and the option to work from home
• 30 days of vacation with a 5-day workweek, plus additional days off on Christmas Eve and New Year’s Eve
• fair pay in accordance with the collective bargaining agreement (TV-L), including an annual bonus and a company-sponsored supplemental pension plan 
• numerous sports and wellness programs (including university sports)
