I started my position at the Marine Bioprospecting group of the CANS-UiT last October to study Arctic viruses and how to use them against bacterial infections.
There are two main research lines to be followed, one focused on phages and the other on giant viruses. Both start with viral isolation and characterization, to be followed by host-pathogen interaction studies and investigation of how to use them against bacteria.
From the phage side the final goal is phage therapy, aiming at the study of phage-bacteria interactions in mucosal conditions for the development of prophylactic phage therapy approaches. From the giant virus side we are interested in understanding the Arctic virome, ideally using local protist hosts to find novel viral groups. Exploring their large and mysterious genomes for finding new biological products is the desired outcome.
