Staff Group(s)


Dr Samantha McLean is a senior lecturer in Microbiology. She is a member of the Antimicrobial Resistance, Omics and Microbiota Research Group and is actively engaged in antimicrobial research. She is course leader for MSc / MRes Molecular Microbiology and MSc / MRes Biotechnology courses and a module leader in both undergraduate and postgraduate Molecular Microbiology modules. Dr McLean is a Masters and undergraduate degree research project supervisor and currently teaches on the following modules:

  • Introduction to Microbiology
  • Applied Microbiology
  • Infectious Diseases and their Control
  • Molecular Microbiology (UG and PG)

Career overview

Dr McLean received a BSc (Hons) degree in Microbiology at the University of Leeds before moving to the University of Sheffield where she completed her PhD in the department of Molecular Biology and Biotechnology. She spent a further six years at the University of Sheffield as a Research Associate investigating the interaction of enterobacteria with small molecules of the innate immune response, including reactive oxygen species, reactive nitrogen species and carbon monoxide.

Dr McLean went on to spend two years at the University of Nottingham as a Research Fellow researching the optimisation of industrial gas fermentation for commercial low-carbon fuel and chemical production through systems and synthetic biology approaches.

In February 2016 Dr McLean took up the position of Lecturer in Microbiology at Nottingham Trent University.

Research areas

Dr McLean is a member of the Pathogen Research Group. Her research interests include investigating the interaction between bacterial pathogens and small molecules of the host innate immune response as well as the exploring the efficacy of novel antimicrobial compounds.

Current research is focussed on evaluating the antimicrobial activity of reactive small molecules and metal compounds both in vitro and when applied to medical devices.

Previous research has included the investigation of oxidative and nitrosative stress in enterobacteria and the use of carbon monoxide releasing molecules as novel antimicrobial agents.

Opportunities arise to carry out postgraduate research towards an MPhil / PhD in the areas identified above. Further information may be obtained on the NTU Research Degrees website
