Lotta Anni Ingeborg Landor

Lotta Anni Ingeborg Landor is a Research Fellow in the Department of Biology at the University of Copenhagen's Faculty of Science, based at the marine research station in Helsingør (Strandpromenaden 5, 3000 Helsingør). Her work centers on microbial ecology within marine environments, focusing on bacteriophage-bacteria dynamics and resistance mechanisms.

Her academic background includes:

• Ph.D. in Microbial Ecology from the University of Bergen (awarded December 15, 2023), with thesis titled 'At what cost? Quantifying cost of resistance in bacterium-phage interactions'.

Landor's research investigates fitness trade-offs in bacterial resistance to phages, employing experimental approaches to quantify metabolic costs and evolutionary consequences. Key areas include host-pathogen coevolution, molecular adaptation in *Escherichia coli*, and ecological implications for microbial communities. Her methodology integrates growth kinetics analysis with protein synthesis profiling to reveal resistance-associated physiological burdens.

Her 2024 publication in Environmental Microbiology Reports demonstrates that phage-resistant *E. coli* strains exhibit significantly altered growth rates and proteomic profiles, confirming substantial fitness costs. This extends her doctoral work into applied contexts, highlighting how resistance mechanisms constrain bacterial adaptability in natural environments.

No scientific awards are documented. As a postdoctoral researcher, she does not supervise graduate students but collaborates with international teams (evidenced by multi-author publications). Her work is institutionally supported through University of Copenhagen resources at the Helsingør marine facility, which provides specialized laboratories for marine microbiological studies.
