Anthony S. Fauci, MD
Chief, Laboratory of Immunoregulation
Director, National Institute of Allergy and Infectious Diseases,
National Institutes of Health, Bethesda, Maryland

A native of Brooklyn, New York, Dr. Anthony S. Fauci received his medical degree from Cornell University Medical College in 1966. He then completed an internship and residency at The New York Hospital-Cornell Medical Center. In 1968, Dr. Fauci came to the National Institutes of Health (NIH) as a clinical associate in the Laboratory of Clinical Investigation (LCI) at the National Institute of Allergy and Infectious Diseases (NIAID). In 1974, he became Head of the Clinical Physiology Section, LCI, and in 1980 was appointed Chief of the Laboratory of Immunoregulation, a position he still holds. In 1984, Dr. Fauci became Director of NIAID, where he oversees an extensive research portfolio of basic and applied research to prevent, diagnose, and treat infectious and immune-mediated illnesses, including HIV/AIDS and other sexually transmitted diseases, illness from potential agents of bioterrorism, tuberculosis, malaria, autoimmune disorders, asthma, and allergies. The budget for NIAID for fiscal year 2003 was approximately $4.6 billion. Dr. Fauci serves as one of the key advisors to the White House and Department of Health and Human Services on global AIDS issues and on initiatives to bolster medical and public health preparedness against possible future bioterrorist attacks.

Dr. Fauci has made many contributions to basic and clinical research on the pathogenesis and treatment of infections and immune-mediated diseases. He has pioneered the field of human immunoregulation by making a number of basic scientific observations that serve as the basis for current understanding of the regulation of the human immune response. In addition, Dr. Fauci is widely recognized for delineating the precise mechanisms whereby immunosuppressive agents modulate the human immune response. He has developed effective therapies for formerly fatal diseases such as polyarteritis nodosa, Wegener's granulomatosis, and lymphomatoid granulomatosis. A 1985 Stanford University Arthritis Center Survey of the American Rheumatism Association membership ranked Dr. Fauci's work on the treatment of polyarteritis nodosa and Wegener's granulomatosis as one of the most important advances in patient management in rheumatology over the previous 20 years.

Dr. Fauci has made seminal contributions to the understanding of how the AIDS virus destroys the body's defenses, leading to its susceptibility to deadly infections. He also has delineated the mechanisms of induction of HIV expression by endogenous cytokines. Furthermore, he has been instrumental in developing strategies for the therapy and immune reconstitution of patients with this serious disease, as well as for a vaccine to prevent HIV infection. He continues to devote much of his research time to identifying the nature of the immunopathogenic mechanisms of HIV infection and the scope of the body's immune responses to the AIDS retrovirus.

In 2003, an Institute for Scientific Information study indicated that in the 20-year period from 1983 to 2002, Dr. Fauci was the thirteenth most-cited scientist among the 2.5 to 3 million authors in all disciplines throughout the world who published articles in scientific journals during that time frame. Dr. Fauci was the ninth most-cited scientist in the field of immunology in the period from January 1993 to June 30, 2003. Through the years, Dr. Fauci has served as Visiting Professor at major medical centers throughout the country. He has delivered many major lectureships all over the world and is the recipient of numerous prestigious awards for his scientific accomplishments, including 32 honorary doctorate degrees from universities in the United States and abroad.


Dennis L. Kasper, MD
William Ellery Channing Professor of Medicine,
Professor of Microbiology and Molecular Genetics, Harvard Medical School
Director, Channing Laboratory, Department of Medicine,
Brigham and Women's Hospital, Boston, Massachusetts

For more than three decades, Dr. Dennis L. Kasper has conducted research in microbiology, infectious diseases, and public health while discharging a broad range of administrative and educational responsibilities. Dr. Kasper is the William Ellery Channing Professor of Medicine and a Professor of Microbiology and Molecular Genetics at Harvard Medical School. As Director of the Channing Laboratory, a research facility with a high international profile, he plays a powerful role in shaping cutting-edge research programs in infectious diseases and epidemiology.

Dr. Kasper has led studies on the molecular basis of bacterial pathogenesis, focusing primarily on group B Streptococcus and Bacteroides fragilis. He has applied the substantial body of knowledge gained in these studies to elucidate the interactions of bacterial surface virulence factors with host defenses. His work has centered around the biochemistry, chemistry, genetics, and immunology of polysaccharides. Years of basic and translational research have culminated in a group B streptococcal polysaccharide-protein conjugate vaccine, targeting the most common bacterial cause of serious neonatal infections. In Dr. Kasper's research on B. fragilis, he has discovered a polysaccharide molecule (PSA) that is critical to the maturation of the mammalian host immune system. This molecule directs the development of an appropriate balance of TH1 and TH2 CD4+ T cells and is a potent stimulant of both innate and adaptive immunity.

Dr. Kasper also directs the New England Regional Center of Excellence for Biodefense and Emerging Infectious Diseases Research and is the Chairman of the National Science Advisory Board on Biosecurity. He has served as Chair of the NIAID's Board of Scientific Counselors and as President of the International Society for Infectious Diseases. Dr. Kasper is also a member of the Institute of Medicine of the National Academy of Sciences.

Dr. Kasper is the editor of the infectious diseases section in the 17th edition of Harrison's Principles of Internal Medicine. He is the author of more than 375 research and clinical publications encompassing an array of topics in infectious diseases and microbiology.


Stephen L. Hauser, MD
Robert A. Fishman Distinguished Professor and Chairman,
Department of Neurology, University of California, San Francisco, San Francisco, California

Dr. Stephen L. Hauser is the Robert A. Fishman Distinguished Professor and Chair of the Department of Neurology at the University of California, San Francisco (UCSF). He is a graduate of the Massachusetts Institute of Technology (Phi Beta Kappa) and Harvard Medical School (Magna Cum Laude). He trained in internal medicine at the New York Hospital-Cornell Medical Center, in neurology at the Massachusetts General Hospital (MGH), and in immunology at Harvard Medical School and the Institut Pasteur in Paris, France, and was a faculty member at the MGH before moving to UCSF in 1992.

A neuroimmunologist, Dr. Hauser's research has focused on the biology of multiple sclerosis (MS). His laboratory described an MS-like disease model in which specific autoantibodies against a quantitatively minor myelin protein are major factors in producing the disease. He demonstrated that autoimmune T cells, previously thought to be the sole trigger for MS, must synergize with disease-causing antibodies to produce typical MS lesions. These findings then led to a clinical trial showing, for the first time, the effectiveness of a therapy directed against antibody-producing lymphocytes in MS. Another area of work has been the study of genetic susceptibility to MS and the identification of DNA variants that influence the risk of developing MS and other autoimmune diseases.

Dr. Hauser has served as President of the Medical Staff at UCSF and currently serves on several scientific advisory boards for nonprofit organizations. He is a fellow of the American Academy of Arts and Sciences and the American Association of Physicians, a member of the Institute of Medicine of the National Academy of Sciences, editor-in-chief of the journal Annals of Neurology, and President of the American Neurological Association.
