**Krystyna M. Kuperberg** (born *Krystyna M. Trybulec*; 17 July 1944) is a Polish-American mathematician who currently works as a professor of mathematics at Auburn University and is the former Alumni Professor of Mathematics there.^{[1]}^{[2]}^{[3]}

Her parents, Jan W. and Barbara H. Trybulec, were pharmacists and owned a pharmacy in Tarnów. Her older brother is Andrzej Trybulec. Her husband Włodzimierz Kuperberg and her son Greg Kuperberg are also mathematicians,^{[2]}^{[3]} while her daughter Anna Kuperberg is a photographer.^{[3]}^{[4]}

After attending high school in Gdańsk, she entered the University of Warsaw in 1962, where she studied mathematics. Her first mathematics course was taught by Andrzej Mostowski; later she attended topology lectures of Karol Borsuk and became fascinated by topology.^{[2]}^{[3]}

After obtaining her undergraduate degree, Kuperberg began graduate studies at Warsaw under Borsuk, but stopped after earning a master's degree.^{[2]}^{[3]} She left Poland in 1969 with her family to live in Sweden, then moved to the United States in 1972.^{[1]}^{[2]}^{[3]} She finished her Ph.D. in 1974, from Rice University, under the supervision of William Jaco.^{[2]}^{[5]}^{[3]} In the same year, both she and her husband were appointed to the faculty of Auburn University.^{[2]}^{[3]}

In 1987 she solved a problem of Knaster concerning bi-homogeneity of continua.^{[2]}^{[3]} In the 1980s she became interested in fixed points and topological aspects of dynamical systems. In 1989 Kuperberg and Coke Reed solved a problem posed by Stan Ulam in the Scottish Book.^{[6]} The solution to that problem led to her well known 1993 work in which she constructed a smooth counterexample to the Seifert conjecture.^{[1]}^{[2]}^{[3]} She has since continued to work in dynamical systems.^{[3]}

In 1995 Kuperberg received the Alfred Jurzykowski Award from the Kościuszko Foundation.^{[2]}^{[3]} Her major lectures include an AMS Plenary Lecture in March 1995, an MAA Plenary Lecture in January 1996, and an ICM invited talk in 1998.^{[1]} In 2012 she became a fellow of the American Mathematical Society.^{[7]}
