PhD / Postdoc position Molecular Physics / Physical Chemistry / Laboratory Astrochemistry

PhD (3 years) or postdoc (up to 2 years) position funded by the German Science Foundation (DFG) is available in the laser molecular spectroscopy group of Otto Dopfer at Berlin Institute of Technology (TU Berlin), Germany.

The predominantly experimental research of our group involves the laser spectroscopic, mass spectrometric, and quantum chemical investigation of molecules, radicals, ions, clusters, and nanostructures in the gas phase, with strong relevance to a broad range of interdisciplinary topics ranging from materials science to biophysics, catalysis, astrochemistry, environmental chemistry, and plasma physics.

This particular DFG project deals with the characterization of the geometric, electronic, optical and chemical properties of hydrocarbon ions of astrochemical interest.

A major driving force is the search for carriers of the long-known but still unidentified Diffuse Interstellar Bands (DIBs).

Available state-of-the-art equipment includes a variety of pulsed and tuneable IR and UV lasers, several ion sources and cryogenic rf-traps, and several types of tandem mass spectrometers.

The group is also strongly involved in international collaborations with groups in Japan, France, Italy, Israel, UK, Netherlands, and is regular user of the IR free electron laser facilities CLIO (France), FELIX (Netherlands), FHI-FEL (Berlin).

Highly qualified and strongly self-motivated candidates hold a MSc (for PhD position) or PhD (for postdoc position) in Physics, Chemistry, or related fields.

Experience in several of the following fields is crucial:

(1) laser spectroscopy

(2) mass spectrometry

(3) ion sources (EI, CI, MALDI, ESI)

(4) ion traps

(5) vacuum physics

(6) molecular beams

(7) cluster science

(8) data acquisition

(9) construction of apparatus

(10) writing of publications, reports, and proposals

(11) communication and presentation skills

Interested and highly qualified candidates are encouraged to send their application to Prof. Otto Dopfer (, including a cover letter, a CV (including a list of publications), a statement of qualifications relevant for the position (max. 1 page), a statement of research interests (max. 1 page) as well as names and complete addresses of two referees.

Only highly self-motivated people are encouraged to apply.

Evaluation of the applications will begin at April 1 (2019) and will continue until the position is filled.

Berlin is an international European city (German capital) and offers an exciting scientific and cultural environment.
