Speaker of the Phycology Section

Andreas Holzinger is Associate Professor at the Department of Botany at the University of Innsbruck, Austria. His main field of research are survival strategies of streptophytic green algae. He conducts studies on abiotic stress (desiccation, light and UV tolerance) and biological interactions at the cell biological, physiological and molecular level. However, he also investigates other groups of algae from a cell biological perspective. Andreas Holzinger received his doctorate from the University of Salzburg in 1995 and completed several research stays abroad during his postdoctoral period, including at the University of Massachusetts (USA) and the University of British Columbia (Canada). In 2002, he moved to the University of Innsbruck, where he habilitated in 2007 and founded his own research group ‘Cell Biology’.

Assessor of the Phycology Section

Claudia Büchel holds a Chair at the Department of Biological Sciences at the Goethe University in Frankfurt. After studying Biology in Mainz, she completed her PhD on the photosynthetic apparatus of a xanthophyte alga. During her first PostDoc position in Szeged, Hungary, she used spectroscopic methods to further study the light harvesting in xanthophytes. This was followed by a period of four years at Imperial College in London, where she used electron microscopy to elucidate the structure of photosynthetic proteins. Having received a Heisenberg Fellowship from the DFG, she worked at the Max Planck Institute of Biophysics in Frankfurt from 2001 to 2004. Since then she is at the Goethe University Frankfurt, working on the light-harvesting systems and the regulation of photosynthesis in diatoms.

Graduate Assessor of the Phycology Section

Vivien Susann Hotter, called Vivi, is a postdoctoral researcher in the Laboratory for Microbial Interactions of Prof. Christian Jogler in Jena. After her Bachelor in Biological Sciences at the University of Konstanz, she studied Marine Biology at the University of Rostock, where she discovered her love for algae and became a member of the Phycology Section. Particularly fascinated by the interactions between algae and bacteria, she completed her doctorate on the subject at the Friedrich Schiller University in Jena. After a successful detour into science management, she was drawn back to phycology and is now looking forward to continuing her involvement in the section.
In her free time, she enjoys riding her pony around the countryside or collecting microbiological samples for her working group all over the world - in compliance with Nagoya, of course.

Speaker of the Phycology Section

Karin Glaser has been a junior professor at the Institute of Biosciences at the Technical University of Freiberg, Germany, since 2023. Karin Glaser completed her doctorate on the diversity of terrestrial protists at the University of Leipzig in 2016. This was followed by a postdoctoral phase at the University of Rostock before she accepted the call to Freiberg. Her research focuses on the diversity and ecophysiological performance of terrestrial microalgae. Particular attention is paid to the biological soil crusts: a microecosystem with important ecological services that is driven by the algae as primary producers.

Graduate Assessor of the Phycology Section

Karin Glaser's main research focusses on terrestrial microorganisms, their ecology and functional role in the ecosystems. She analyses biodiversity with a set of molecular methods. At the moment, she is working on microorganism associations in soil crusts, which are composed of algae, cyanobacteria, fungi, protists and heterotrophic bacteria. How the ecological functions of biological soil crusts are related to biodiversity is her current research question. She studied Biology in Leipzig and did her PhD at the Helmholtz-Center for Environmental Research in Leipzig (UFZ). Since 2014 she is working in Rostock.

The Phycology Section was founded in Vienna on the suggestion of Professor Dr. Ludwig Kies, Professor Dr. Eberhard Schnepf, Professor Dr. W. Wiessner und Prof. Dr. J. Willenbrink on 1984. The idea was born during an earlier Botanikertagung of the mother Society DBG. Three month later Professor Kies organised a poll among interested people.

The aim of the Section - to promote Phycology in teaching and research was already documented in its first bylaws. Professor Kies was awarded with the first Hans Adolf von-Stosch Medal for his leading engagement in the founding of the Phycology Section.

Secreatary of the Phycology Section

Klaus Herburger is Juniorprofessor at the Institute for Biological Sciences at the University of Rostock, Germany. His research focus is on cell walls of green algae and land plants, in particular their enzymatic remodelling during cell growth and high potential as a sustainable raw material. Moreover, he is interested in developing non-invasive methods for localising cell wall components. Herburger received his doctorate from the University of Innsbruck (Austria) in 2016, working on cellular adaptations of terrestrial green algae to their habitats. This was followed by a five-year postdoc phase at the University of Edinburgh (Scotland) and the University of Copenhagen (Denmark), where he studied the cell walls of land plants and their main storage carbohydrate, starch, before accepting his appointment in Rostock in 2022.

Assessor of the Phycology Section

Thomas Leya manages the Extremophile Research group and is the curator of the Culture Collection of Cryophilic Algae (CCCryo) at the Fraunhofer IZI-BB in Potsdam. Main topics of his research are cold-adapted microalgae from polar and high alpine regions of our planet. He addresses taxonomic and phylogenetic questions as well as applied aspects based on the adaptation mechanisms of this extremophile algae group. He transfers the results from this applied field into industrial products such as active components in cosmetics, omega-3-fatty acids and pigments for the food sector. Genomics and transcriptomics complete his research topics on snow algae. After an education as an export trader, Leya studied biology in Hamburg and performed field studies on antifouling substances from marine red algae in Sydney (Australia). Since 1999 he works with snow algae and founded the algae collection CCCryo. In 2003, he did his doctorate on snow algae from Spitsbergen at the Humboldt-Universität zu Berlin. Since 2004 Leya is group manager at the Fraunhofer Society. Since 2017 he is also active as an expert for algae identification at the DIN (Deutsches Institut für Normung e.V.).

Graduate Assessor of the Phycology Section

Charlotte Permann is a PhD student at the Department of Botany, University of Innsbruck, Austria. Her current research focuses on the sexual reproduction (conjugation) of a streptophyte green algal class (Zygnematophyceae), which has been established as immediate sister lineage to land plants. The studies include the collection of field samples and the cultivating of conjugating Zygnematophyceae, as well as the analysis of their conjugation morphology and the structural and biochemical properties of the formed zygospores. She received her Master's degree in 2020 in the research group 'Cell Biology of Plants' on conjugation experiments in Zygnema, followed by her PhD thesis in the eponymous project 'Sexual Reproduction of Zygnematophyceae (Charophyta)'.
