Say hello to our PhDs and post-docs
The young generation in our group works on a range of different topics withing terrestrial and marine microbial ecology. Methodologies include polar field work, genomics and modeling, to name a few.
Limitation of resources in nature entails trade-offs associated withtraits. In microbial systems, the development of resistance against aparasite (i.e. virus) comes with costs, commonly on the growth rate andhence competitiveness of the host (i.e. bacteria). These competitive anddefensive traits, and the trade-off between them, are important piecesof the puzzle in understanding the process of microbial evolution, withimplications on wide-ranging fields including microbial ecology,antibiotic resistance, and vaccine production. The goal of my PhDresearch is to characterize this trade-off by gathering data on where,how, and to what degree does the trade-off express itself in themicroorganism. I will do so by using molecular methods and the modellingapproach to study the growth, infectivity, and resistance of variousco-evolving virus-bacteria systems.
My PhD project involves a lot of experimental work. I’m studying bacteria and their viruses (phages) interactions. As bacteria are exposed to phages, they develop phage resistance. In my project, I’m studying the implication of phage – as well as antimicrobial – resistance in bacteria in chemostat and batch cultures.
The flourishing interaction between microbial warfare in global climate change has become a major concern. This doctoral study undertakes, research about understanding the functional role of permafrost soil microbiome having a definite role in Carbon cycle and emission of carbon from thawing permafrost which has been sequestered there since ages. Climate change has shown altered diversity within the soil microbiome, this related to rapid changing of Arctic. Understanding the effect of temperature on microbial biodiversity and metabolic processes, will direct in improving knowledge about how the production and emission of biogenic methane takes place, one of my study will include methane flux experiments at the Pingos in Svalbard, whereas fieldwork is based in exploring and studying different Pingo sites in Svalbard.

My research interests are in understanding trophic dynamics, from viruses to zooplankton in oceanic and coastal marine ecosystems. I am interested in using a range of different tools, including microscopy, flow cytometry and molecular biology (including qPCR and droplet digital PCR) to further our understanding on rates and changes of marine microbial communities. My current research activities include enhancing our knowledge of the link between viruses and gelatinous zooplankton, how mixotrophy affects marine food webs, and understanding the interplay between mortality factors such as predation and viral infection in natural, laboratory and mesocosm communities.
