Peter T. Doran is an American Earth scientist who is Professor of Geology and Geophysics and John Franks Endowed Chair at Louisiana State University.
Doran was the lead author of a research paper about Antarctic temperatures that was published in the journal Nature in January 2002.
Because he and his colleagues found that some parts of Antarctica had cooled between 1964 and 2000, his paper has been frequently cited by opponents of the global warming theory, such as Ann Coulter and Michael Crichton.

He was nominated by former Apollo astronaut Harrison Schmidt to be a member of the Planetary Protection Subcommittee of the NASA Advisory Council in 2008 and served until 2017.
In 2018 he was appointed to represent the U.S. as a member of the Committee on Space Research (COSPAR) Panel on Planetary Protection.
Both an Antarctic stream and glacier were named for Doran by the U.S. Geological Survey to commemorate his many significant research contributions conducted on the continent.
His father, Terence Doran, was a renowned gynecologist and obstetrician with a private practice and a faculty position at the University of Toronto, and was a pioneer of prenatal diagnosis.
