The 2012 W.T. and Idalia Reid Prize was awarded to Ruth F. Curtain (University of Groningen, The Netherlands) for her "fundamental contributions to the theory of infinite dimensional systems and the control of systems governed by partial and delay differential equations." Curtain titled her prize lecture "Large Algebraic Properties of Riccati Equations." The Reid Prize was established in 1993 to recognize outstanding work, or other contributions to, the broadly defined areas of differential equations and control theory; it has been given annually since 2000.

Barbara Keyfitz, the Dr. Charles Saltzer Professor of Mathematics at Ohio State University, received the 2012 SIAM Prize for Distinguished Service to the Profession from SIAM president Nick Trefethen. Keyfitz was recognized "for her long-term and pervasive advocacy of ap-plied mathematics in several leadership roles. As the Director of the Fields Institute in Toronto (2004–2008), Keyfitz revitalized applied mathematics programming at the Institute with initiatives such as the successful Fields–MITACS Industri-al Problem-Solving workshops. The innovative Canada-wide graduate industrial research internship program for students in the mathematical sciences was created by MITACS–NCE while she served on its Board of Directors. The program has since expanded from applied mathematics to cover all disciplines. She was President of the Association for Women in Mathematics (2005–2006). In SIAM, Keyfitz served as Vice President for Programs (1998–2003), and was instrumental in forming closer links between SIAM's US-based and Mexican communities, in particular through the organization of numerous SIAM–SMM conferences. Currently, as President of ICIAM, she is leading applied mathematics globally."

The 2012 SIAG/FME Junior Scientist Prize was awarded to Sergey Nadtochiy (University of Oxford, UK) for "his impressive contributions to Mathematical Finance and his original, sophisticated and rigorous mathematical analysis of challenging problems in volatility modeling and derivative pricing theory." Nadtochiy is the first recipient of the prize, which was established by the SIAM Activity Group on Financial Mathematics and Engineering in 2010 to recognize outstanding work in the field by a junior researcher.

Vojtěch Rödl of Emory University (left) and Mathias Schacht of the University of Hamburg, Germany, received the 2012 George Pólya Prize for "their seminal work on the regularity method for hypergraphs." Rödl and Schacht, according to the prize citation, "have produced a central body of results developing, extending, and consolidating Szemerédi's regularity method for hypergraphs. They have also shown how this method leads to remarkable results like the generalized hypergraph removal lemma and the theorem that every decidable, hereditary property of k-uniform hypergraphs is testable with one-sided error."
