Digital microscopy
Virtual slide based diatom microscopy using semi-automatic slide scanning techniques. Developed a technique to use digital diatomology with
technical help of Michael Kloster.
2019 – now Diatom community analysis using a BIIGLE-based methodology (biigle.de)
2017 – 2021 Diatom community and morphometrical analysis with SHERPA (https://www.uni-due.de/phykologie/sherpa)
Molecular methods (DNA-metabarcoding on benthic diatoms)
Diatom barcoding with rbcL and 18S V4 markers on samples of the temporary rivers. Started
2022 – adaptation for temporary river molecular analysis
2013 – Diatom culture based barcoding
Vitality appraisal method
To ascertain the proportion of diatoms in a living, dying and dead state, I have been working on the adaptation of several microscopy based and photosynthesis based methods to quantify and confirm the quality for analysis of the sample.
