Anna Székely
My research focuses on the microbiology of diverse aquatic systems from wastewater to pristine freshwater springs, from large lakes to small ponds. My goal is to improve our understanding of the forces shaping microbial communities and their function as well as to contribute to develop unbiased methods for aquatic microbial analyses.


I am an Associate Professor (docent) in Biology with a focus on Limnology. The overarching theme of my research career has been aquatic microbial ecology. I have special interest in understanding the effect of microbial-viral interaction on community assembly and function, the diversity of carbon processing hot-spots within inland water systems and the way microbial carbon processing at such hot-spots happen.
In addition, I have always been dedicated to reveal and address the methodological problems of environmental microbiology to achieve as unbiased view of microbial and viral communities as possible.

Furthermore, I am engaged in science dissemination and outreach. Throughout the years I have organised and participated in diverse outreach activities about microbial diversity and antibiotic resistance. I am also one of the developers of Cure me! an educational game about antibiotic resistance created in collaboration with the Uppsala Antibiotic Center.
Finally, in response to the COVID-19 pandemic, I initiated the measurement of SARS-CoV-2 in the wastewater of Uppsala. I am also the scientific lead of the Environmental Virus Profiling research area of SciLifeLab. The results of our measurements are regularly updated on the CRUSH COVID dashboard and all data is available on the Swedish COVID Data Portal.
