Lucy is a co-lead of the RVC AMR research group, and co-lead of the UK-Nigeria One Health AMR Interest Group.

Her research focuses on understanding the molecular epidemiology of antimicrobial resistance and using One Health systems approaches to tackle this complex problem. She is particularly interested in the role that food animal production plays in contributing to the emergence and spread of AMR, and the increased burden of AMR on health and livelihoods in LMICs. Lucy is also interested in improving understanding of the epidemiology of bovine tuberculosis in England to support TB policy making.

Lucy is module leader for the BSc3 module "Epidemiology: the Bigger Picture". She teaches on a variety of topics in the areas of epidemiology and publlic health across the College at undergraduate and postgraduate level, as well as delivering teaching externally at LSHTM.

• AMFORA: Applying a One Health systems approach to formulate strategies for mitigating risk to human health of AMR in Aquaculture

  

  The aim of AMFORA is to use a ‘systems-thinking’ approach to map aquaculture systems and identify hotspots for the emergence and selection of resistance and human exposure to antimicrobials and antimicrobial-resistant organisms.

  This will enable the identification of potential drivers of AMU and interventions to reduce AMU.

• Antibiotic usage on dairy farms in GB: improving data capture and exploring drivers

  

  The aims of this PhD were to determine the accuracy of antibiotic usage data being recorded by dairy farmers on farm, identify factors influencing accurate recording, assess the drivers and barriers to record and share such data and to explore the economic cost of recording. Antibiotic usage (ABU) has become recognised as the main driver for the selection and spread of antibiotic resistance (ABR) within the human and livestock sectors.

• Epidemiology of Tuberculosis in Cattle

  

  We study the epidemiology of tuberculosis in cattle using a combination of fieldwork and the analysis of big data. Bovine tuberculosis (bTB) is caused by infection with Mycobacterium bovis. It is the most pressing animal health problem in Great Britain. Around 40,000 cattle test bTB-positive each year and are slaughtered in an effort to control this disease. This comes at a cost to the taxpayer of around £100 million per year in surveillance testing and compensation.

• Molecular analysis of the prevalence of antibiotic resistance among Enterobacteriaceae in food-producing animals and humans in Southeast Nigeria

  

  A study of extended-spectrum β-lactamases (ESBL)-producing bacteria in food-producing animals and in-contact humans in Southeast Nigeria.

  The indiscriminate use of antimicrobial agents in humans and livestock imposes a selective pressure for the emergence of antimicrobial resistance among bacteria. In Nigeria, the production of extended-spectrum β-lactamases (ESBL) has been recognised as a common mechanism of resistance to third-generation cephalosporins among Enterobacteriaceae.
