Sellers attended Cranbrook School, Cranbrook, Kent, United Kingdom, until 1973, and achieved a bachelor's degree in ecological science from the University of Edinburgh in 1976.
The University of Edinburgh, founded in 1582, is the sixth oldest university in the English-speaking world and one of Scotland's ancient universities.
The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom or Britain, is a sovereign state in Europe.
Ecology is the scientific analysis and study of interactions among organisms and their environment.
In 1981 he gained a doctorate in biometeorology from the University of Leeds.
A doctorate or doctor's degree or doctoral degree is an academic degree awarded by universities that, in most countries, qualifies the holder to teach at the university level in the degree's field, or to work in a specific profession.
Biometeorology is the interdisciplinary field of science that studies the interactions between the biosphere and the Earth's atmosphere on time scales of the order of seasons or shorter.
The University of Leeds is a redbrick university located in Leeds, West Yorkshire, England.
In 2011, Sellers retired from the NASA Astronaut Corps.
The NASA Astronaut Corps is a unit of the United States National Aeronautics and Space Administration that selects, trains, and provides astronauts as crew members for U.S. and international space missions.
An astronaut or cosmonaut is a person trained by a human spaceflight program to command, pilot, or serve as a crew member of a spacecraft.
Before joining the astronaut corps, Sellers worked at NASA Goddard Space Flight Center on research into how the Earth's biosphere and atmosphere interact.
The Goddard Space Flight Center is a major NASA space research laboratory established on May 1, 1959 as NASA's first space flight center.
This work involved climate system computer modeling and field work utilizing aircraft, satellites and ground support input.
Computer simulations reproduce the behavior of a system using a model.
