* Gerontologists: These are scientists who study the biological, psychological, and social aspects of aging. They are probably the closest single group to focusing specifically on longevity.
* Geriatricians: These are medical doctors specializing in the care and treatment of older adults. While their focus is on health in later life, understanding longevity factors is crucial to their work.
* Biogerontologists: This subset of gerontologists focuses on the biological mechanisms of aging. They often work at a cellular and molecular level.
* Epidemiologists: These researchers study the patterns, causes, and effects of health and disease in populations, including factors related to lifespan and life expectancy.
* Demographers: These scientists study population size, structure, and distribution, including factors influencing longevity and mortality rates.
* Geneticists: They investigate the genetic factors contributing to lifespan and age-related diseases.
* Nutritionists and Dietitians: They explore the role of diet in healthy aging and longevity.
In short, longevity research is interdisciplinary, drawing on expertise from many different fields.
