Job description:

The candidate will work at the Leibniz-IPHT and the Department of Anesthesiology an Intensive Care Medicine at Jena University Hospital directly on intensive care patients, applying spectroscopic tools to the multivariate analysis of biological gases to elucidate the host response to severe infections and sepsis1. In an excellent clinical-scientific environment, the candidate will contribute to shaping the newly established intensive care laboratory that is unique in Germany, at the BMBF-funded Leibniz Centre for Photonics in Infection Research (LPI). The close proximity to the Institute for Clinical Chemistry and Laboratory Diagnostics at the Jena University Hospital and the affiliation with the Field-Resolved Optical Precision Metrology Group within the Spectroscopy and Imaging Department at the Leibniz-IPHT will provide access to state-of-the-art clinical laboratory diagnostics and cutting-edge infrared vibrational spectroscopy techniques2,3, respectively. The position is furthermore affiliated with the DFG-funded Cluster of Excellence "Balance of the Microverse" whose core mission is to elucidate fundamental principles of the interactions and functions in microbial communities in diverse habitats, ranging from oceans and groundwater to plant and human hosts.

Your field of activity includes:

  • Applying infrared vibrational spectroscopy in combination with mass spectrometry to the multivariate analysis of biological gases.
  • Collabaoration with partners within the DFG-funded Cluster of Excellence Balance of the Microverse in setting up and performing headspace analysis of in-vitro bacterial and cell cultures, to study their response to pathogen and drug stimulation.
  • Development of sample collection and storage protocols for the spectroscopic analysis of the exhalome of intensive-care patients.

Your qualification:

  • Completed doctorate in the natural sciences or medicine.

Desired knowledge and skills:

  • Laboratory experience with clinical analytics and/or biomedical application of spectroscopic methods, ideally with gases
  • Enjoy interdisciplinary work with a focus on applications in the biomedical field
  • Strong motivation, commitment an independence
  • Very good written and spoken English

What we offer:

  • An open welcome culture and an interdisciplinary work environment: Located on the Beutenberg Campus in Jena, the Leibniz IPHT is home to more than 400 employees from around the world working at the interface of physics, biochemistry, technology, data science and medicine to develop the photonic technologies of tomorrow.
  • Thorough and comprehensive personal training: Transferring good practices in scientific working and outreach is one of our main focus point.  We'll teach everything that is needed for a career inside and outside of academia in a respectful and enjoyable way. Moreover, plenty of workshops and opportunities for scientific exchange are offered by the Leibniz IPHT, as well as the Abbe School of Photonics and the Graduate Academy of the Friedrich-Schiller University Jena.
  • World-class equipment and facilities: The Leibniz IPHT offers a large variety of physics, chemistry, and biology labs at highest level. It also has state-of-the-art fiber drawing and clean room facilities (including lithography facilities) as well as microfluidics fabrication and big data computing facilities.
  • A family-friendly working environment with a variety of offers for families: parent-child room, campus kindergarten places, family events, advice on family care stuations from trained care guides and much more.
  • Flexible working time models, 30 days vacation/year, special annual payment and bridge days.
  • Jena – City of Science: A young and lively town with a vibrant local cultural agenda!
