Dr Alexander Donald Williams completed his PhD on antimicrobial resistance (AMR) in agriculture at the University of Nottingham, UK, before moving to Hong Kong to take up a position as a Post-doctoral Fellow at the Laboratory of Data Discovery for Health and latterly the University of Hong Kong. Dr Williams has continued to develop his research on AMR, with a strong focus on One Health projects. This work has expanded to include research on emerging microbial pathogens and microbial ecology in climate-vulnerable regions. Most recently, this has involved international collaborations in support of work in both the Arctic and Antarctic.
