Lesley Hoyles

Associate Professor

School of Science & Technology

Staff Group(s)


Dr Hoyles is an Associate Professor in Microbiology, focusing on microbiome research. She has a unique combination of skills (microbiology, computational biology) that allows her to use various omics technologies (microbiomics, transcriptomics, metabolomics) in vitro and in vivo to understand how members of the microbiome function and influence human health and disease. This integrated systems-level approach has allowed her to define the contribution of the microbiome and its metabolites to non-alcoholic fatty liver disease, metabolic retroconversion and integrity of the blood–brain barrier.

October 2012 – November 2014: Postdoctoral Research Associate in Bioinformatics and Translational Systems Biology, Imperial College London, UK.

October 2011 – September 2012: Advanced MRC scholar, MSc (DIC) Bioinformatics and Theoretical Systems Biology, Imperial College London, UK.

October 2009 – September 2011: Government of Ireland Postdoctoral Fellow in Science, Engineering and Technology (IRCSET scheme), University College Cork, Ireland.

Research areas

Dr Hoyles started her career as a taxonomist, characterizing novel fastidious Gram-positive anaerobes isolated from clinical and veterinary sources.

Her GlaxoSmithKline-funded PhD, at the University of Reading, focused on using in vitro fermentation systems to understand the effect of an anti-obesity therapy on the human gut microbiota and its lipolytic activity. She then secured a Fellowship at University College Cork to work in the bacteriophage research group of Professor Douwe van Sinderen, developing methods to improve recovery and characterization of bacteriophage populations within the human gut.

Since training as a computational biologist, Dr Hoyles has worked extensively in the field of systems biology. Most recently, she has worked on numerous animal and human studies integrating microbiomic, metabolomic and transcriptomic data to better understand how the microbiome and its metabolites influence intestinal and systemic health.

Her current research interests include/incorporate:

  • Coriobacteriia associated with the gut microbiota
  • Shotgun metagenomics (microbiome and virome)
  • Transcriptomics (eukaryote and prokaryote)
  • Effect of gut-derived microbial metabolites on host health
  • Use of in vitro systems to study diet–microbiome interactions
  • Intestinal Klebsiella pneumoniae and Klebsiella oxytoca and their bacteriophages

Opportunities to undertake postgraduate research towards an MPhil/PhD exist within the School of Science and Technology. Further information can be obtained from the NTU Doctoral School.
