He received his BA in 1963 from Yale University and PhD in 1966 from Princeton University Robert Gunning supervised his thesis Hamilton has taught at UC Irvine, UC San Diego, Cornell University, and Columbia University

Hamilton's mathematical contributions are primarily in the field of differential geometry and more specifically geometric analysis He is best known for having discovered the Ricci flow and starting a research program that ultimately led to the proof, by Grigori Perelman, of the Thurston geometrization conjecture and the solution of the Poincaré conjecture In August 2006, Perelman was awarded, but declined, the Fields Medal for his proof, in part citing Hamilton's work as being foundational

Hamilton was awarded the Oswald Veblen Prize in Geometry in 1996 and the Clay Research Award in 2003 He was elected to the National Academy of Sciences in 1999 and the American Academy of Arts and Sciences in 2003 He also received the AMS Leroy P Steele Prize for a Seminal Contribution to Research in 2009

On March 18, 2010, it was announced that Perelman had met the criteria to receive the first Clay Millennium Prize for his proof of the Poincaré conjecture[1] On July 1, 2010, Perelman turned down the prize, saying that he believes his contribution in proving the Poincaré conjecture was no greater than that of Hamilton, who first suggested a program for the solution In June 2011, it was announced that the million-dollar Shaw Prize would be split equally between Hamilton and Demetrios Christodoulou[2]
