Dr Hamilton is an Associate Professor in the School of Pharmacy, leading research into antimicrobials, which includes exploring the experiences of people diagnosed with drug-resistant infections and chronic carriage; lab-based research on antimicrobial drug-delivery; alongside a range of antimicrobial stewardship and prescribing related research. He has collaborated nationally and internationally, notably with NHS England, local hospitals and pharmacies, and the UK Clinical Pharmacy Association's Pharmacy Infection Network, for which he is the research lead. 

He teaches across the MPharm (Pharmacy) focusing on infection, antimicrobial therapies and stewardship, clinical pharmacy practice and prescribing, and evidence based medicine, audit, and research. 

Outside of ²ÝÁñÊÓƵ, Ryan is a Consultant Antimicrobial Pharmacist at Kettering General Hospital NHS Foundation Trust and chairs the regional Northamptonshire Antimicrobial Medicines Optimisation Group. Ryan's previous roles as a clinical pharmacist include OPAT, acute and general medicine, respiratory medicine, and COVID ICU pharmacist.
