Four New Members Join Board of Directors to Continue to Fight COVID-19 and Promote Field of Infectious Diseases


Arlington, Va. – Oct. 8, 2020 – The Infectious Diseases Society of America is pleased to announce Barbara Alexander, M.D., FIDSA, as the society’s new president beginning Oct. 25. Dr. Alexander will be joined by dedicated, experienced board members as well as newly elected representatives who will lead IDSA’s commitment to promoting excellence in patient care, education, research, public health, and prevention relating to infectious diseases.

“The critical role of infectious diseases physicians and scientists has never been more apparent as it is today, in the midst of a global pandemic.

Concurrently, these same professionals are also anticipating the next outbreak and fighting infections in every community around the globe. I am honored to lead this society at such a pivotal time,” said Dr. Alexander.

In addition to leading the society through the pandemic, Dr. Alexander will also work with the Board of Directors to continue the implementation of the society’s strategic initiatives. These include leading the fight against antimicrobial resistance and advocating for increased awareness of the value of the ID physician with the aim of achieving fair compensation and attracting young physicians and scientists to the field.

She is principal investigator of the Duke University NIHT32-funded Transplant Infectious Diseases Interdisciplinary Research Training Program.

Dr. Alexander’s research interests include clinical and translational research related to infectious complications of solid organ and hematopoietic stem cell transplantation, with a particular interest in the prevention and rapid diagnosis of invasive fungal infections. She has served as Chair of the Clinical and Laboratory Standards Institute Subcommittee on Antifungal Susceptibility Tests, Associate Deputy Editor of the Clinical Infectious Diseases journal, consultant to the FDA Antimicrobial Drugs Advisory Committee, and as faculty mentor to the NIH T32-funded Tri-insitutional Molecular Mycology and Pathogenesis Training Program.
