The Geneva Observatory in Geneva, Switzerland, announces the availability of a research position at the postdoctoral level, open to applicants of all nationalities. The succesful candidate will work on projects aimed at studying starburst galaxies nearby, at intermediate redshift (z~2-3), or in the early Universe (z>6), involving multi-wavelength observations and/or theoretical modeling. He/she may in particular work with ground-based near-IR and longer wavelength observations including HST, Spitzer and Herschel data from approved and upcoming projects. He/she will also have access to state-of-the-art modeling tools including 3D radiation transfer, SED fitting, and evolutionary synthesis codes. The candidate will mostly work in collaboration with Prof. Daniel Schaerer in Geneva and within international collaborations. The Geneva Observatory and the associated Laboratory of Astrophysics of the Swiss Federal Institute of Technology in Lausanne carry out observational, interpretative and theoretical research in the fields of extra-solar planets, stellar evolution, stellar physics, high energy astrophysics, galaxy evolution and dynamics, and observational cosmology. The appointment will be for one to three years starting around September 2010 (negotiable). It is renewable. Qualified candidates are encouraged to send their application including a CV and publication list, description of research experience and interests, and contact information of three references preferably via email to the above address. Applications received by 1 May, 2010 will receive consideration. Informal enquiries with Daniel Schaerer (daniel.schaerer@unige.ch) are welcome.
