Dr Louis Kreitmann

Consultant in Critical Care

Biography

I am a Critical Care Consultant at Guy’s and St Thomas’ NHS Foundation Trust with dual training in Internal Medicine and Intensive Care Medicine, and an early-career clinical academic based at King’s College London. I hold an MSc in Experimental Medicine from McGill University (Canada) and a Master of Public Health (Biostatistics) from the Université de Lyon (France). I completed my PhD in 2025 at Imperial College London’s Centre for Antimicrobial Optimisation (CAMO), supported by a bioMérieux scholarship, where I investigated digital technologies to enhance multiplex PCR panels for syndromic infection testing.

My research focuses on the epidemiology, diagnosis, and management of severe infections in critically ill patients, with particular emphasis on immunocompromised populations and antimicrobial resistance. I contribute to and lead multicentre European observational studies examining infection patterns, antimicrobial use, and clinical outcomes in intensive care units.

My long-term vision is to develop innovative diagnostic strategies that integrate rapid microbiological detection with host-response profiling, and to evaluate their impact on antimicrobial optimisation and patient outcomes through multicentre randomised controlled trials within the NHS and international critical care networks.
