Katrina Deane Barron (born 1965) [1] is an American mathematician and mathematical physicist whose research concerns vertex operator algebra. She is an associate professor of mathematics at the University of Notre Dame. [2]
Barron has a double bachelor's degree from the University of Chicago: a 1986 B.S. in mathematics and a 1987 B.S. in physics. [3] She completed her Ph.D. at Rutgers University in 1996, with the dissertation The Supergeometric Interpretation of Vertex Operator Superalgebras, jointly supervised by James Lepowsky and Yi-Zhi Huang. [4]
Before becoming an assistant professor of mathematics at the University of Notre Dame in 2001, [3] she was a postdoctoral researcher with Geoffrey Mason at the University of California, Santa Cruz, supported by a University of California Presidential Postdoctoral Fellowship. [5]
Barron was named as a Fellow of the Association for Women in Mathematics, in the 2025 class of fellows, "for her tireless advocacy for gender equality, mentorship of women in algebra, representation theory, and mathematical physics, and active participation and leadership in initiatives aimed at supporting women in mathematics".
