The paper develops PhageScan to study human antibody responses to bacteriophages, finding widespread IgG reactivity and identifying immunogenic epitopes.

This study examines gut microbiome changes in hospitalized COVID-19 patients using shallow and deep shotgun sequencing to assess their predictive value for clinical outcomes.

The paper investigates the triadic interactions between gastric bacterial microbiome, phageome, and host genotype, finding that phages are influenced by both bacterial hosts and human genetic variants.

This study investigates how gut phages transfer to the bloodstream and identifies immune factors that limit their persistence in circulation.

The paper identifies cross-reacting IgG hotspots in SARS-CoV-2 proteins that are both immunogenic and associated with immune evasion, suggesting their utility in vaccine design and diagnostics.
