Mark John Pallen

Mark John Pallen is a Vice-Chancellor's Fellow and Consultant Medical Microbiologist at the School of Veterinary Medicine, University of Surrey. His work bridges microbial genomics, taxonomy, and public health, with a focus on bacterial ecology and evolution.

• Academic Rank: Research Fellow
• Key Collaborations: International teams in microbiology, veterinary science, and infectious disease genomics

Research Interests span microbial genomics, bacterial nomenclature, and microbiome studies. His projects include tracking SARS-CoV-2 variants, analyzing Escherichia coli diversity in human and animal hosts, and developing scalable systems for naming uncultured taxa.

• Methodologies: Metagenomic assembly, whole-genome sequencing, phylogenetic profiling
• Applications: Antimicrobial resistance surveillance, pathogen evolution, and host-microbe interactions

Publication Trends highlight his leadership in microbial taxonomy, with recent work on the Candidatus system and the reorganization of prokaryotic phyla. He advocates for genomics-driven nomenclature reforms and has contributed extensively to understanding microbiomes in equine, porcine, and primate hosts.

Notable Contributions include:

• Genomic epidemiology of swine dysentery
• Development of Golden Gate-based gene editing tools
• Advances in Leviviricetes RNA virus taxonomy
• Analysis of E. coli virulence and resistance in sub-Saharan Africa

His interdisciplinary approach connects microbiology, computational biology, and planetary health, with a strong emphasis on practical solutions for global health challenges.
