Alesia Walker

Alesia Walker is a Senior Scientist at the Research Unit Analytical Biogeochemistry within Helmholtz Munich. She specializes in non-targeted metabolomics and uses LC-coupled high-resolution mass spectrometry to investigate host-microbiota interactions.

• Education: Ph.D. in Analytical Chemistry (2013), M.Sc. in Nutrition Science (2009), both from Technical University Munich

Research Focus

Her work centers on understanding diet-related metabolic disorders and inflammatory bowel diseases (IBD) through large population cohorts and methodological innovations in metabolomics. She develops analytical techniques for global and lipid-specific metabolite profiling to uncover microbial metabolite impacts on host health.

Scientific Contributions

Key projects include:

• PhaStGut: Studying bacteriophage-bacteria coexistence in gut microbiomes (2020)
• miTarget 5042: Exploring microbiome as a therapeutic target in IBD
• DECODE: Stratifying patients with immune complex-mediated glomerular diseases
• APROSUS: Investigating microbiome-derived protective substances for asthma prevention
