Richard Lawrence Taylor (born 19 May 1962) is a British[2] mathematician working in the field of number theory.

[7] He earned his Ph.D. in mathematics from Princeton University in 1988 after completing a doctoral dissertation, titled "On congruences between modular forms", under the supervision of Andrew Wiles.

[4] One of the two papers containing the published proof of Fermat's Last Theorem is a joint work of Taylor and Andrew Wiles.

[10] In subsequent work, Taylor (along with Michael Harris) proved the local Langlands conjectures for GL(n) over a number field.

Taylor, together with Christophe Breuil, Brian Conrad and Fred Diamond, completed the proof of the Taniyama–Shimura conjecture, by performing quite heavy technical computations in the case of additive reduction.
