Sir Philip Henry Montgomery Campbell FRS FRAS FInstP[4] (born 19 April 1951)[2] is a British astrophysicist.

[2] He went on to study aeronautical engineering at the University of Bristol, graduating with a Bachelor of Science (BSc) degree in 1972.

[1] His doctoral and postdoctoral research was on the physics of the ionized upper atmosphere and effects on radio propagation, using the latter as a probe of the lower ionosphere.

Due to publicity about a 2009 interview with Chinese State Radio[20] during which he expressed support for the CRU scientists, he resigned just hours after the panel was launched.

[21] Campbell was a founding member and, from 2015 to 2019, chair of the board of trustees of the research-funding charity MQ: Transforming Mental Health.

[34] In January 2010 he was a guest on Private Passions, the biographical music discussion programme on BBC Radio 3.
