Current tasks

I am PhD student focusing on the importance of seed banks for the expansion of harmful algae blooms in the Baltic Sea. My target organism is a toxin producing dinoflagellate (Alexandrium ostenfeldii) which occurs in shallow waters of the Baltic Sea. My work includes sampling and cultivation of A. ostenfeldii, as well as experimentation and genetic characterisation of this organism. My aim is to unravel life cycle aspects and population dynamics of A. ostenfeldii in the Baltic Sea. My supervisors are Anke Kremp and Sanna Suikkanen.

I have a BSc degree in ecology and a MSc degree in limnology (2012). Both were awarded by the University of Vienna and I that’s also where I gained experience in the field of wastewater cleaning and algae cultivation. Before starting my PhD I extended my background in applied phycology in Austria. First when working with algae biomass used as feedstock for biogas production at the University of Natural Resources and Life Sciences and later at the company Erber Future Business, where the establishment of an algae research laboratory was one of my main tasks.

Research topics
