I have a PhD from the University of Copenhagen in the Department of Veterinary and Animal Sciences, under the supervision of Dorte Frees.
I have worked on projects aimed at characterizing the mechanisms by which bacteria develop resistance. In this work, I have used a variety of molecular biology techniques, including cloning, Northern and Western blotting, as well as a range of microscopy techniques such as immunofluorescence, fluorescence, time-lapse, electron, and super-resolution (SR-SIM) microscopy.
I have also contributed to setting up a system for tracking the growth of multiple bacterial strains simultaneously and have experience using Fiji for image analysis. My greatest strengths lie in the laboratory work, optimizing workflows for practical applications.
Utilizing image-based solutions for resolving single molecules
Investigating mechanisms in cells division and antimicrobial resistance in Staphylococcus aureus and Streptococcus pneumoniae
Optimizing and creating recombinant spider-silk producing E. coli
