AG Biophysik, I. Physikalisches Institut (IA)

Our profile

The successful applicant will be employed by the RWTH Aachen, but the work will be conducted at Heinz Maier-Leibnitz Zentrum (MLZ) in Garching, nearby Munich. The work will be performed in close cooperation with the Jülich Centre for Neutron Science (JCNS) of the Forschungszentrum Jülich.

The research activities of the AG Biophysik aim to establish a fundamental, physics-based understanding of the function of bio-macromolecular systems. In this respect proteins and (protein based) macromolecular complexes, also within in their cellular context, are of particular interest for our research topics (

At the MLZ ( Jülich Centre for Neutron Science (JCNS) is operating a suite of high performance neutron scattering instruments. In addition, it is actively pursuing a research program in soft matter science offering a highly interdisciplinary and international environment. We are an innovative research group with experience in both fields SANS and IR spectroscopy and in-situ techniques and equipped with excellent experimental methods embedded in the international research environment of the JCNS.

Your profile

-University Degree (Master or equivalent) in Physics or Chemistry and a PhD in a related field ideally with a focus on the development of new measurement set-ups
-Knowledge of scattering techniques is not required but would be a plus
-Knowledge in IR spectroscopy and designing optical set-ups would be desired
-Data analysis using computer programs will also be an important aspect of the project
-Experience with computer programming for data analysis (python or similar) is advantageous
-IR spectra modelling and interpretation skills would be desirable
-Good communication skills in English are a requirement
-Cooperative and structured working style and passion for science and new ideas
-Fun in writing publications should be present in the successful candidate

Your responsibilities

The successful candidate will develop a novel in-situ infrared (IR) spectrometer at the small-angle neutron scattering (SANS) instruments operated by JCNS in order to monitor the structural changes involved with the different states of proteins by a combination of neutron scattering and infrared absorption on the very same sample.

In detail your job involves:
-Build-up of a novel IR spectrometer based on Quantum Cascade Lasers
-Development of sample cells allowing IR and SANS in situ on the very same sample
-Sample characterization by CD-spectroscopy, UV-visible and IR spectroscopy
-Performing neutron scattering experiments at the MLZ in Garching and world-wide
-Presentation of the results at conferences and publication of scientific articles
-Interdisciplinary teamwork and supervision of Bachelor and Master students
-Chance of participating in (international) conferences and project meetings

What we offer

The successful candidate will be employed as a regular employee.
The position is to be filled as soon as possible and limited to 3 years .
This is a full-time position.
Applicants must have a doctorate/Ph.D. or equivalent.
The salary corresponds to level EG 13 TV-L.
