Hayley Gans, MD

Hayley Gans, MD, is a professor of pediatrics at Stanford University Medical Center. She spends her clinical time on the pediatric infectious diseases service and co-directs the Pediatric Infectious Diseases Program for Immunocompromised Hosts. She is also the director of fellowship education for the Department of Pediatrics and the associate program director for the Pediatric Infectious Diseases Program. The focus of her research has involved investigations into the innate and adaptive immunity to viral vaccines in several different populations. Initial studies included infants receiving an early measles vaccination regimen, which then expanded to include preterm infants, HIV-infected adults and children, and children and adults undergoing liver and renal transplantation. In addition, studies also included an expanded repertoire of viral antigens, such as cytomegalovirus, poliovirus, varicella, and mumps. Recently, she has expanded her research to address viral infections in pediatric solid organ transplant recipients. Additional research efforts are directed at bioinformatics in immunocompromised cohorts and outcome measures in ambulatory pediatrics, as well as studies in the arena of medical education.

Elaine I. Tuomanen, MD, CM, is the ALSAC Endowed Chair of Infectious Diseases at St. Jude Children’s Research Hospital in Memphis, Tennessee. She is also director of the Children’s Infection Defense Center at St. Jude and adjunct professor of pediatrics and molecular sciences at the University of Tennessee.

After receiving her medical degree from McGill University, she served as pediatric intern and resident at Montreal Children’s Hospital. Dr. Tuomanen began her pediatric infectious diseases fellowship training at the University of Virginia in Charlottesville and completed her training as the Bristol Fellow of Infectious Diseases and the Parker B. Francis Pulmonary Research Fellow at Rockefeller University, where she began her work on Streptococcus pneumoniae pathogenesis under the mentorship of Dr. Alexander Tomasz. While an associate professor at Rockefeller University, she headed the Laboratory of Molecular Infectious Diseases, where she continued her groundbreaking work on the interplay between pneumococci and innate immunity. Among her seminal contributions are studies that link pneumococcal virulence factors to specific host receptors, the inflammatory bioactivities of cell wall, and the increased susceptibility of children with sickle cell disease to pneumococcal disease. Her work has been continuously funded by the National Institutes of Health for 30 years, and she is the author of over 200 peer-reviewed publications and over 100 reviews and book chapters.

In recognition of her impact on medical sciences, Dr. Tuomanen was elected a member of the Association of American Physicians and fellow of the American Academy for Microbiology. She was the recipient of the 1998 Maxwell Finland Award from Infectious Diseases Society of America, the 1997 E. Mead Johnson Award for Outstanding Research in Pediatrics from the American Academy of Pediatrics and the inaugural Pediatric Infectious Diseases Society (PIDS) Distinguished Research Award in 2014.

Dr. Tuomanen has devoted many years to understanding the mechanisms by which Streptococcus pneumoniae invades the human host, establishes infection, and manifests as invasive disease. In recent work, she and her research group have identified the molecular mechanisms by which S. pneumoniae access the cerebrospinal fluid and have developed vaccine antigens that protect against S. pneumoniae colonization, pneumonia, and meningitis. In addition, she has demonstrated a strong commitment to educating and mentoring the research efforts of our younger colleagues as the founder of the annual St. Jude-PIDS ID Research Conference, initiating the St. Jude-PIDS Transplant ID Symposium, and creating the PIDS-St. Jude Fellowship Award in Basic Science.
