Prof Faust undertook senior house officer and specialist registrar training in paediatrics at Great Ormond Street Hospital, St. Mary's Hospital Paddington, University College London, Hammersmith Hospital, the Whittington Hospital, Royal London Hospital, Tower Hamlets PCT and Edgware General Hospital.

Prior to joining the Trust in 2006, he completed clinical research training as MRC clinical research fellow and clinical lecturer at Imperial College London, St Mary's Campus.

Prof Faust is part of UHS’s paediatric immunology and infectious diseases team, who support and advise on antibiotic management for all children and babies treated in Southampton as inpatients. They become more involved with the care of children in hospital when an infection is complicated or difficult to treat, or when there is a diagnostic dilemma. The team of three consultants is also responsible for overseeing children receiving antibiotics at home.

In outpatients, Prof Faust and his team see children with a range of infections and immune conditions, including

  • infections like HIV and Lyme disease
  • rare or unusual infections (confirmed or suspected)
  • genetic disorders of the immune system (known as primary immunodeficiency disorders)
  • infections children are born with (congenital infections, for example cytomegalovirus).

The team also sees children who have been admitted to hospital previously with suspected or confirmed serious infections like sepsis or meningitis, including children who have previously been treated on intensive care. They can also see children more urgently in clinic if necessary, for example those with suspected tuberculosis or Kawasaki disease.

Key achievements

  • Prof Saul Faust set up and leads the Southampton tertiary paediatric immunology and infectious diseases service, creating a full time NHS consultant post (2010) and a clinical academic consultant post (2016). The team care directly for children with complex infections and primary immunodeficiency disorders, in Southampton and in collaboration with colleagues across Wessex.
  • Prof Faust has been director of the Southampton NIHR Clinical Research Facility since 2008. The facility is managed as an NHS ward environment for clinical research and trials in children and adults, patients and healthy volunteers. As associate medical director for research and development and deputy director of the Southampton Biomedical Research Centre (2017-22), Prof Faust works with colleagues across the Trust and university to provide the best possible environment for patients to take part in clinical trials and other research. In April 2020, Prof Faust will become clinical director of the National Institute for Health Research Wessex Local Clinical Research Network.
  • Prof Faust is clinical lead for paediatric immunology and infectious diseases at University Hospital Southampton/Southampton Children’s Hospital. He's been a member of the national NHS England Clinical Reference Group for Paediatric Medicine since 2013, working with colleagues to ensure high quality paediatric medical subspecialties in Southampton and across England.
  • Prof Faust was the NICE Guideline Committee chair for sepsis in children and adults (published 2016) and the NICE Guideline Committee chair for Lyme disease in children and adults (published 2018). He's been involved in developing many other national guidelines for children, including being co-author of the the Wessex regional antibiotic guidelines for children (available via the award-winning microguide app), the national algorithm for management of meningococcal disease in children and national guidelines for managing paediatric bone and joint infections. He was also a member of the NICE guideline development group for diarrhoea and vomiting in children under five.

Prof Faust is a clinical researcher in paediatric infectious diseases and immunology, developing local and national collaborative clinical trials in paediatric infectious diseases. He also conducts paediatric and adult vaccine trials as part of the UK academic paediatric vaccine group. Prof Faust conducts trials of new medicines for children to treat infections such as bronchiolitis and serious bacterial infections, taking part in many national and international trials on behalf of UHS.

Prof Faust co-leads the clinical biofilm research group at the University of Southampton, working with colleagues across the faculties of medicine, biological sciences and engineering. This work is trying to find new treatments for patients with infections caused by bacteria sticking together on body surfaces, such as in cystic fibrosis.

He's also a member of Genomics England's Clinical Interpretation Partnerships for primary immunodeficiency, paediatric sepsis and paediatrics, part of the 100,000 Genome Project. This research aims to directly benefit patients and has been featured on BBC and ITN news.
