Janek Paul Dann

Janek Paul Dann is a PhD student at the Department of Effect-Directed Analysis since April 2018. His PhD is part of the student college linked to the IP EXPOSOM with three other PhD students. The subject of his work is the relation of internal and external exposure signatures of fish. The internal exposure finally causes toxic effects in the organism; the external exposure is the direct or indirect origin of the effect-causing chemical compounds. The main objective is the development of a combined approach using a modified QuEChERS-extraction + clean-up, liquid/gas chromatography coupled to high-resolution mass spectrometry (HPLC/GC-HRMS), bioassays and chemoassays, which will be applied on water, sediment and different organs of fish to get an understanding of how external contamination patterns translate into internal exposure.

Janek studied Chemistry at the Leipzig University (M.Sc.) and at the Georg-August University Göttingen (B.Sc.). In his master thesis, he developed a new identification tool for the identification of unknown substances, which can be applied in nontarget-screening of environmental samples.
