Summary
The Emmy Noether Junior Group led by Dr. Brandt Gaches at the University of Duisburg-Essen is seeking a postdoctoral researcher to investigate the microphysics and chemistry of cosmic-ray interactions with icy dust grains. This DFG-funded position focuses on high-energy astrochemical processes, particularly the interaction of cosmic rays with dense molecular gas, utilizing chemical modeling and theory.
Designation
Postdoctoral Researcher (f/m/d)
Research Area
Microphysics and Chemistry of Cosmic-Ray Interactions with Icy Dust Grains; High-Energy Astrochemical Processes; Cosmic-Ray Astrochemistry; Chemical Modelling and Theory; Astrochemistry Low-energy electron Cross-Section database.
Location
Duisburg, Germany (University of Duisburg-Essen, Faculty of Physics)
Eligibility/Qualification
- 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.
Job Description
As the postdoctoral researcher, you will contribute to an atomic-scale understanding of the interaction of energetic particle irradiation with icy dust grains. Your main tasks 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.
- Characterizing the chemical structure of the simulated irradiated ices and the composition of the desorbed gas-phase molecules.
- Performing a broad parameter study for different radiation particle types, ice mantle compositions, and ice thicknesses.
The results of this research are expected to significantly enhance the understanding of complex organic molecule buildup via cosmic-ray irradiation.
We Offer:
- A position in the public sector with reliable working conditions.
- A varied, multifaceted field of work 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, salary group 13, gross 59.324–84.319€), including an annual bonus and a company-sponsored supplemental pension plan.
- Numerous sports and wellness programs (including university sports).
