Gunther Uhlmann was awarded the Bôcher Prize by the American Mathematical Society "for his fundamental work on inverse problems and in particular for the solution to the Calderón problem in the papers 'The Calderón problem with partial data' (with Carlos E. Kenig and Johannes Sjöstrand, Annals of Math. (2) 165 (2007) no. 2, 567-591) and 'The Calderón problem with partial data in two dimensions' (with Oleg Yu. Imanuvilov and Masahiro Yamamoto, J. Amer Math. Soc. 23 (2010), no. 3, 655-691). The prize also recognizes Uhlmann's incisive work on boundary rigidity with L. Pestov and with P. Stefanov and on nonuniqueness (also known as cloaking) with A. Greenleaf, Y. Kurylev, and M. Lassas."
