Postdoc Position - Cloud Droplets and Redox Pairs in the Venusian Atmosphere

Austrian Academy of Sciences

Graz, Austria

The successful candidate will be appointed in the FWF Austrian-Czech project “Redox Disequilibrium in the Clouds of Venus - A Sign of Life?” and will join the research groups led by Dr. Peter Woitke and Doz.Dr. Helmut Lammer at the Space Research Institute (IWF) in Graz. This project will investigate whether Redox Disequilibrium Pairs (RDPs - H2S, NH3 and PH3 in combination with O2 have been detected in the Venus atmosphere) can be produced by photo-processes on the surfaces of acidic cloud particles, as novel experiments by our Czech project partners around Dr. Martin Ferus (Institute of Physical Chemistry in Prague) suggest.

Your profile

  • The applicant must hold a PhD in Geosciences or Astrophysics;
  • The successful candidate is expected to bring know-how and hands-on experience with computational petrology and/or aqueous chemistry;
  • Previous experience with chemical modelling of planetary atmospheres;
  • Experience with compiled computer languages, including non-python.

Your Tasks

  • Collect thermo-chemical data and implement aqueous chemistry into the chemical and phase equilibrium code GGchem (Woitke et al. 2018, A&A 614, A1);
  • Work with the ARGO code on the Venusian atmosphere (Rimmer et al. 2021, PSJ 2, 133), to include cloud formation and surface chemical processes on cloud particles;
  • Collaborate with our Czech and UK colleagues via team meetings and working visits;
  • Connect our work to the ESA EnVision Space mission.
