Richard T. Johnson

Richard T. Johnson is a physician and scientist at the Johns Hopkins University School of Medicine. Johnson has been a faculty member in the Department of Neurology since its inception in 1969 and is the former head of the department. His research into the effects of viruses on the central nervous system has been published in over 300 scientific articles, and Johnson is both a journal and book editor and the author of an influential textbook, Viral Infections of the Nervous System.[1]

Education and training

Johnson, who was raised in Colorado, received his undergraduate degree cum laude from the University of Colorado in Boulder in 1953. He remained in Colorado to earn his medical degree in 1956 at the University of Colorado School of Medicine in Aurora, Colorado. He interned in internal medicine at Stanford University.

From 1957-1959, Johnson conducted research at the Walter Reed Army Institute of Research, Department of Virus Diseases, in Washington, DC. Johnson completed his residency in neurology at Harvard Medical School and Massachusetts General Hospital. He conducted research at the Institute of Advanced Studies at the Australian National University from 1962-1964.[2]

Career

Johnson's first faculty appointment was as an assistant, then associate, professor of neurology at Case Western Reserve University.

In 1969, Johnson moved to the Johns Hopkins School of Medicine, accepting the Dwight D. Eisenhower Professorship of Neurology and founding a new Department of Neurology with Guy McKhann. Johnson was director of the department from 1988 until 1997 and remains a faculty member. He is also a professor of microbiology in the Department of Molecular Biology and Genetics and holds a joint appointment in the Department of Immunology and Infectious Diseases at the Johns Hopkins Bloomberg School of Public Health. Johnson has been a visiting professor at universities in Peru, Thailand, Iran, and Germany.

Johnson is on the staff of the Johns Hopkins Hospital and until 1997 was Neurologist-in Chief at the Johns Hopkins Hospital. He was certified by the American Board of Psychiatry and Neurology in 1966.

In 1997, Johnson became the founding director of the National Neuroscience Institute of Singapore, which he directed until 2000. He also assumed editorship of the Annals of Neurology.

Johnson's monograph Viral Infections of the Nervous System was published in 1982. A second edition followed in 1998.

During his career, Johnson has supervised the post-doctoral training of many notable scientists, including Janice E. Clements, Diane Griffin, and Opendra "Bill" Narayan.

Research

Throughout his career, Johnson has contributed to understanding of infections of the central nervous system.

Transmissible spongiform encephalopathies

Johnson met D. Carleton Gajdusek, 1976 Nobel Prize winner for his work on transmissible spongiform encephalopathies (TSEs, or prion diseases), while working at Walter Reed in the 1950s. In 1964, Johnson himself observed a case of Kuru, a prion disease, in Papua New Guinea. When Johnson became a professor at Johns Hopkins, his lab held joint lab meetings with Gajdusek's lab. Johnson helped to examine the first chimpanzee to show signs of Kuru after Gajdusek experimentally inoculated it with brain matter from a human victim. Johnson later chaired a US Institute of Medicine committee on TSEs. The committee released a report in 2004, stressing the need for further and expanded research into prion diseases[3][4]
