Christopher Schafhauser, professor in the Department of Mathematics, has been recognized by two organizations for his work in algebras.
The Canadian Mathematical Society has awarded him the Israel Halperin Prize for several contributions in the field of C*-algebras. The Selection Committee wrote:
"As a postdoc at U. Waterloo and then York U., he established himself a new force in the field of C*-algebras with several major results: a new, concise proof of the Tikuisis-White-Winter Theorem, embedding every separable exact C*-algebra with amenable trace and UCT into a simple monotracial AF algebra, and a characterization of the ideal property for crossed products (with M. Kennedy). Schafhauser was a critical contributor to the conceptual and self-contained C*-algebra classifcation theorem of Carrion et al. More recently, he established a beautiful KK-rigidity theorem for simple nuclear C*-algebras."
The Institute of Mathematics of the Polish Academy of Sciences awarded Schafhauser the Barbara and Jaroslav Zemánek prize for his outstanding contributions to the classification and structure theory of C*-algebras, particularly to the Elliott classification program. According to their website:
"The jury emphasized his outstanding results on AF-embeddability of the UCT C*-algebras and his original and innovative approach to the classification of simple nuclear C*-algebras, which led to breakthrough in the field."
