Lewis Arthur is a PhD student in the Centre for Host-Microbiome Interactions (FoDOCS) and the Clinical Pharmacology Therapeutics Research Group (FoLSM) supervised by Dr David Moyes and Dr Sylvia Dobbs respectively. His PhD research is 'A clinic to laboratory-based approach towards a structured aetiopathogenic model for Parkinson’s disease by microbial kingdom, their interactions and ecological shifts with a view to targeted intervention.'

Lewis completed his BSc in Biochemistry at Queen's University Belfast with the following research project, 'Investigating Alternative Pathways for the Biosynthesis of the Endocannabinoid Ligand Anandamide in Phylum Platyhelminth' identifying a highly conserved non-canonical anandamide biosynthesis pathway within phylum platyhelminth using Hidden Markov Models, representing novel therapeutic targets in anthelmintic-resistant infections.

He also has an MSc in Microbiome and Disease from King's College London which he completed in 2025. His research project. 'Exploring the Gut Mycobiome in Parkinson's Disease', validated and optimised a pan-fungal PCR assay targeting the Internal Transcribed Spacer (ITS) regions of ribosomal DNA.
