抽象表現主義
Sillman began studying and working in painting in the mid 1970s. Her influences include the New York School (art), Abstract expressionism, and Willem de Kooning and Philip Guston in particular. Sillman does not consider herself an Abstract Expressionist, stating, "I wanted to learn about both Abstract Expressionism and the critique of easel painting—not because I wanted to emulate them, but because I didn’t like them."
