Professor Muhamed-Kheir Taha is the Head of the Invasive Bacterial Infections Unit at the Institut Pasteur in Paris, France. He is also Head of the French National Reference Centre for Meningococci and Haemophilus influenzae and Head of the WHO Collaborating Centre for Meningitis. Professor Taha received his MD degree from the University of Damascus in 1983, his PhD from the University of Diderot, Paris in 1990 and his habilitation from the University of Descartes, Paris in 1997. Professor Taha is the current President of the European Meningococcal and Haemophilus Disease Society (EMGM). He served as a voting member of French Advisory Committee on Immunization (the CTV) from 2007 to 2017. His research focuses on the molecular pathogenesis of Neisseria meningitidis and Haemophilus influenzae as well as on the molecular epidemiology of meningococcal and H. influenzae infections.

Dr. Tamma is an Associate Professor of Pediatrics and the Director of the Pediatric Antimicrobial Stewardship Program at The Johns Hopkins University School of Medicine. She is also an Associate Professor in the Department of Epidemiology at The Johns Hopkins Bloomberg School of Public Health. Her research focuses on: (a) elucidating the mechanisms of resistance in gram-negative organisms (including both the Enterobacterales and glucose non-fermenting bacteria), (b) developing and enhancing rapid phenotypic and genotypic methods to identify gram-negative resistance to enable critically-ill patients to be placed on appropriate antibiotic therapy as early as possible, and (c) identifying optimal treatment strategies for patients infected with multidrug-resistant gram-negative infections, including leading a multicenter NIH-funded Phase 2 study of bacteriophage therapy. She has past and present funding from the NIH, FDA, CDC, and AHRQ to investigate these areas. She had the opportunity to work in the national and international arena to advance including: serving as an Editor at Antimicrobial Agents and Chemotherapy and The Journal of the Pediatric Infectious Diseases Society; serving as 1 of 12 international voting members of the Clinical Laboratory and Standards Institute that provides international guidance on phenotypic and genotypic methods for identifying antimicrobial resistance; serving as a voting member of the NIH-funded Antibacterial Resistance Leadership Group Gram-Negative Resistance Committee; and serving as the Co-Chair for the Infectious Diseases Society of America Antimicrobial Resistance Guidance.
