Samantha McLean


Dr Samantha McLean is a senior lecturer in microbiology, her research group focusses on the development and evaluation of new antimicrobial technologies that reduce microbial contamination of materials. Her group has expertise including classical microbiology, antimicrobial testing, transcriptomics, standards (BSI, ISO) and the design and use of bespoke models for real-world microbiology application. Samantha is also a member of the British Standards Institute panel working group (products and biofilms).

Antimicrobial resistance is a formidable threat, projected to escalate globally into the primary cause of mortality unless swift action is taken. Our interdisciplinary projects are dedicated to developing innovative strategies for infection prevention and control that will slow the spread of resistance and save lives.
