Postdoctoral research positions in Exoplanets
The exoplanet team of the University of Geneva has an opening for four postdoctoral researchers to work on detection 
and characterization of exoplanets through high-precision radial velocity measurements. Focusing on the low-mass range 
of exoplanets and using the high-precision spectrographs CORALIE, HARPS, HARPS-N, ESPRESSO, SPIROU, and NIRPS, 
our team is strongly involved in blind radial velocity surveys as well as in the follow-up of transiting candidates from the NGTS, K2 
and TESS photometric surveys. The selected applicants are expected to work on: the optimization of the data-reduction, 
calibration and RV-extraction from both visible and near-infrared high-resolution spectrographs; the mitigation of the stellar activity; 
the combination of RV data with photometric, astrometric and direct imaging measurements, including dynamical developments for 
the characterization of multi-planetary systems. They will be strongly involved in the science exploitation of large programs and 
guaranteed observing time of aforementioned spectrographs and in the development of specific tools for the Data and Analysis 
Center for Exoplanets (DACE; for validation and combined analysis of exoplanets.
The Department of Astronomy of the University of Geneva offers a modern and vibrant work environment, with a wide range of 
activities including theory, numerical simulations, observations and instrumental developments in the domains of exoplanets, 
stellar physics, galactic dynamics, observational cosmology and high-energy astrophysics. Our exoplanet team is renowned for its strong involvement in exoplanet detection, the determination of the planet physical properties, the characterization of exoplanetary 
atmospheres, and the development of world-class instrumentation. We are also co-leading the Swiss-wide National 
Centre of Competence in Research (NCCR) PlanetS (, dedicated to the study of the origin, evolution, and characterization of planets inside and outside our Solar System, providing the applicants with opportunities to develop collaborations with members of the large PlanetS community.
Applicants are expected to have experience in observation, data reduction and analysis, especially of high-precision radial velocities. 
The duration of the postdoc contract is 2 years, with possible extension to a third year depending on available funds. Candidates 
should be less than 3 years after obtaining their PhD at start of the employment. The positions are funded by Swiss National Science 
Foundation with a gross salary around 80,000 CHF and are open for immediate start.
Interested candidates can contact Prof. Stéphane Udry (stephane.udry(at), Prof. Francesco Pepe (francesco.pepe(at), or Prof. François Bouchy (francois.bouchy(at)
 and send their application to Dr. Sophie Saesen (sophie.saesen(at) The application should contain *in a singe pdf file*:
- a curriculum vitae;
- a publication list;
- a motivation letter;
- a short research statement describing past achievements and future projects.
Applicants should arrange for up to two letters of recommendation to be sent to the same address. The deadline is 15 March 2019 but applications will accepted until the positions are filled.
