Marisa Isabell Keller

Marisa Isabell Keller is a Postdoctoral Researcher in the Hansen Group at the University of Copenhagen's Faculty of Health and Medical Sciences. Her work focuses on the intersection of microbiome research and liver diseases, with particular emphasis on gut microbiome dynamics in clinical contexts.

Her research interests span multiple dimensions of microbiome science, with primary focus on gut microbiome analysis in liver disease contexts. She investigates the bacterial and fungal components of the gut ecosystem (mycobiome), employing advanced omics technologies for biomarker discovery in steatotic liver diseases. Her work bridges clinical research with computational biology, examining how microbial communities influence disease progression and treatment responses, particularly in alcohol-related liver conditions and cirrhosis.

Analysis of her publication record reveals a clear trajectory from foundational microbiome research (2019-2022) toward increasingly clinical applications (2023-2025). Her earlier work focused on methodological advances in microbial genomics and taxonomic profiling, while her more recent publications demonstrate translation into clinical settings, particularly through randomized controlled trials examining microbiome-targeted interventions for liver disease. This progression reflects the growing recognition of microbiome science in clinical hepatology.

Her collaborative network is extensive, with co-authorship on publications involving multiple international consortia including the MicrobLiver Consortium and GALAXY Consortium, indicating her integration into major research initiatives in the field.

Based at Blegdamsvej 3B, Mærsk Tårnet in Copenhagen, she works within what appears to be a multidisciplinary research environment focused on translational medical science, with particular emphasis on the gut-liver axis and microbiome-related therapeutic approaches.
