Alan William Reid (born June 14, 1962) is a Scottish-American mathematician working primarily with arithmetic hyperbolic 3-manifolds. He is the Edgar Odell Lovett Chair of mathematics at Rice University, 2017—present.^[1]

Reid grew up in Buckie, Scotland.^[2] He obtained his doctorate from the University of Aberdeen,^[3] supervised by Colin Maclachlan,^[4] on the topic of Arithmetic Kleinian Groups and their Fuchsian Subgroups. He was a Royal Society University Research Fellow at Cambridge 1992-96. He was awarded the Sloan Research Fellowship in 1997,^[5] and became one of the (inaugural) Fellows of the American Mathematical Society in 2013.^[6]

Alan Reid's research primarily focusses on low-dimensional topology, hyperbolic manifolds and profinite groups. He proved that the figure-eight knot is the only knot whose complement is an arithmetic hyperbolic 3-manifold.^[7] With Martin Bridson, Ben McReynolds and Ryan Spitler, he found the first examples of non-elementary Kleinian groups which are determined by their finite quotients among finitely generated residually finite groups.^[8]

He has published more than 100 papers,^[9] and supervised 21 PhD students to completion as of 2023.^[10][11]
