Christopher is technical lead on PHE’s IHR Strengthening team for Ethiopia. Much of his work has included the design of comprehensive needs assessment tools, supporting laboratory activities involving biologically material potentially hazardous to human and animal health, and developing and implementing training programmes to improve in-country clinical and diagnostic microbiology lab capabilities in low medium resource countries. He has most recently been part of the team that developed PHE COVID-19 laboratory training (lab-based and eLearning) in the NADP Training team's capacity as a WHO Collaborating Centre in applied Biosafety and Training. Between 2020 and 2021 Christopher was laboratory supervisor of the high throughput SARS-CoV-2 clinical molecular diagnostic labs at PHE-Porton, running the Roche COBAS 6800/8800 platforms. Christopher is an honorary professor of Virology at the University of Plymouth working on emerging viruses and visiting professor at the University of San Francisco, Quito, Ecuador, where he delivers a masters virology course. Prior to joining PHE, Christopher carried out his post-doc on hazard group 3 arboviruses at the Centres for Disease Control and Prevention (CDC) in the USA.

Prior to working as a trainer, Suzanna was a Biomedical Scientist in an NHS Clinical microbiology laboratory where she qualified and completed a Masters in Biomedical Science.  Later she moved into research at Porton for the characterisation and antimicrobial susceptibility testing of ACDP hazard group 3 bacteria before becoming a Senior Biomedical Scientist in the Rare and Imported Pathogens Laboratory (RIPL). RIPL provides specialist diagnostic capabilities for the UK and on-call service for Viral Haemorrhagic Fevers.  Here she was also heavily involved with EU projects dealing with quality assurance for high threat pathogens and the UK outbreak of Anthrax in people who inject drugs, going on to conduct her Professional Doctorate study in B.anthracis in blood cultures.
