Open positions at the Chair of Aroma and Smell Research

for Bachelor, Master, Diploma and State Exam theses for students from the fields of Chemistry (especially Food Chemistry, Analytical Chemistry and Organic Chemistry), Molecular Sciences, Food Technologies, Nutrition Sciences, Material Sciences and related programs. In general, we offer theses in various areas of research related to our current research projects. Also check available options for theses with our colleagues at Fraunhofer IVV. If you are interested to do a thesis in a specific topic, please contact Dr. Helene Loos or Prof. Danijela Gregurec.

Synthesis and Characterization of Odor Active Substances, Examination of Structure-Odor Relations

The aim of the work is the synthesis of structurally related volatile compounds potentially included as odorants in food, plant materials or synthetic materials (such as plastics). The synthesized target components are characterized by analytical parameters such as mass spectra, NMR spectra or retention indices. In addition, their odor properties are recorded and possible structure-odor-relationships will be identified. Furthermore, the human sensory evaluation of the compounds and the determination of odor thresholds are performed.

Applicants need in-depth knowledge of the synthesis of organic compounds and must have sufficient laboratory experience to ensure safe and independent work. Experience with sensory examinations and analytical methods, in particular gas chromatography, as well as MS and NMR would be an advantage.

For queries and applications, please contact Dr. Helene Loos.

Qualitative and Quantitative Analysis of Odorous Substances

The aim of the work is the analytical characterization of odor-active substances, which are potentially important in food, plant materials or synthetic materials such as plastics for the aroma or the smell of the product. The target components are identified and quantified in the respective materials by analytical methods, in particular gas chromatography-olfactometry (GC-O) or GC-MS. In order to be able to quantify the substances in the respective materials by means of GC-MS, the synthesis of stable isotope-labeled analogues of the odor-active substances may also be part of the work.

Applicants must be able to work independently and safely in chemical laboratories and must have in-depth knowledge of the analysis of organic, in particular volatile compounds. Initial experiences with gas chromatographic analyses as well as experiences in sensory examinations and other analytical methods, in particular MS and NMR, are preferable.
