Dr. Rahme has a distinguished record of academic achievement in bacterial regulatory systems that govern virulence and host responses to infection and burns. Her research group studies pathogen and host mechanisms that mediate or restrict bacterial pathogenesis in order to obtain knowledge that can be applied toward the development of host-protective interventions targeting critical pathways. She has an international reputation for her pioneering work on the development of anti-virulence drugs that block pathogenesis but not cell viability, as well as the use of non-vertebrate hosts to study bacterial-host interactions. Anti-virulence drugs will limit the use of antibiotics and it is believed that they will decrease the development of antibiotic resistance, while preserving the beneficial flora. Moreover, her group developed the first pipeline that permits the identification of patients with a high risk of developing multiple infections after burns, days before infection occurs. This information permits personalized therapy, and facilitates the determination of appropriate treatment courses, particularly in regard to antibiotic use. As such her pioneering research is bridging clinical and basic science and opens new avenues for novel therapeutics.
Her research is funded by the National Institute of Health (NIH), Department of Defense (DoD) and Cystic Fibrosis Foundation (CFF) among others. She served thus far as mentor to more than 15 pre-doctoral, pre-medical and graduate students and more than 30 post-doctoral research fellows (PhD and MD), fifteen of whom have obtained assistant professorship positions, while other past trainees have chosen clinical, administrative or biotechnology positions.
She is on the Advisory and Editorial Board of PLOS Biology, Journal of Pathogens, F1000 and Pathogens and she has served on NIH, NSF and on several national and international foundation review panels and also served as an associate editor and ad-hoc editor or reviewer for many scientific journals. Her publications have been cited more than 7,000 times. She is the leading inventor of more than 10 patents and patent applications.
Laurence received her BS in Biology from the University of Naples, Italy, and earned her Master’s in Molecular Genetics from the Institute of Genetics and Biophysics, CNR and University of Naples, Italy and her PhD in molecular host-microbe interactions from the University of California at Berkeley, USA. She conducted a postdoctoral fellowship at MGH and Harvard Medical School in the Departments of Molecular Biology and Genetics, respectively. At MGH she is also affiliated with the Department of Molecular Biology and Division of Infectious Diseases. She also holds a scientific staff position at Shriners Hospital for Children, Boston. Dr. Rahme is the Scientific Founder, and a member of the scientific advisory board of Spero Therapeutics located in Cambridge, MA.
