John Feather Wheater (born 1958, in London) is a British physicist, and Professor specialising in particle physics at the University of Oxford.

[5] He undertook a DPhil degree on electroweak radiative corrections, supervised by Chris Llewellyn Smith during 1979–81.

In 1985, Wheater joined the academic staff of the Department of Physics at Oxford University, initially as a lecturer.

[13] In 2018–19, Wheater was invited to be a visiting professor at the QMATH-center in the Department of Mathematical Sciences at the University of Copenhagen, Denmark.

[14][15] Wheater's former doctoral students include Neil Ferguson,[3] who initially studied physics at Oxford University, but later became an epidemiologist and professor of mathematical biology at Imperial College London and was an influential scientist in the UK government strategy for the COVID-19 pandemic in the United Kingdom.
