About
Work tasks
I’m currently working as a PhD-candidate in the ACMS group with Ingrid Bakke and Johannes Kabisch as my supervisors. I’m working with several strains of Janthinobacterium, Atlantic salmon eggs and fry, and the water mold Saprolegnia. My aim with this work is to learn more about the interplay between the bacteria, salmon, and the water mold, and to look into the antagonism of the bacteria toward the water mold. I’m especially interested in the causes of this antagonism, but also the density-based communication system that this bacteria has. In this work, I’m going to do genome analysis, molecular genetics, and more traditional microbial techniques. Furthermore, I’m going to work with germ-free salmon eggs and yolk sac fry.
Background
I’m from Trondheim and finished my master’s in industrial chemistry and biotechnology in spring of 2020 at NTNU. In my master’s project, I worked on studying the production of the antimicrobial pigment violacein in Janthinobacterium isolated from salmon yolk sac fry. During my master’s project, I worked a lot with the cultivation of bacteria with different media and conditions. Additionally, I used PCR to amplify the violacein operon for sequencing. I also have a bachelor in chemical engineering. After finishing my master I worked as a researcher in AKMS with a focus on the analysis of bacterial communities, gene expression in salmon yolk sac fry, and microbial and chemical water quality in a recirculating aquaculture system.
Interests
My interests outside of work are among other music and concerts, off-piste skiing, football, and lifting weights.
