Erica Jen facts for kids

Erica Jen (Chinese: 任峻瑞; Rén Jùnrùi, circa 1952 – November 12, 2023) was an American applied mathematician. She was a researcher at Los Alamos National Laboratory, a faculty member at the University of Southern California, and a scientific director and faculty member at the Santa Fe Institute.

Jen's research was based on the mathematical analysis of chaotic and complex behavior. Research areas have included the singular integral equations for crack propagation, the mathematics of cellular automata - a class of dynamical systems that evolve according to simple local interaction rules - and mechanisms of robustness in natural and social systems.

Early life and education

Jen was born in 1952 to Chih-Kung Jen, a Chinese-born physicist who played a leading role in the 1970s in reestablishing scientific exchanges between the U.S. and China. After her junior year at Yale University, Jen went to Beijing University for further education. She became the first American national to be allowed to study in China since 1949 and the first foreigner since the Cultural Revolution

After returning to the U.S., Jen obtained a Ph.D. in applied mathematics from Stony Brook University of the State University of New York and was the first postdoctoral fellow at the Center for Nonlinear Studies at Los Alamos National Laboratory.

Career

Jen served for the period 1983–86 as a university scholar and assistant professor of mathematics at the University of Southern California. In 1986, Jen became a staff member in the theoretical division and acting deputy director of the Center for Nonlinear Studies at Los Alamos National Laboratory.

In 1995, Jen joined the Santa Fe Institute, a leading interdisciplinary research center for the study of complex adaptive systems. She first served as vice president for academic affairs and then as a research professor. Jen was the principal investigator for innovative programs in evolutionary dynamics, social networks, and distributed learning. During her tenure at the Santa Fe Institute, Jen developed the groundbreaking SFI program on the robustness of physical, biological, ecological, and social systems. After 2003, Jen served as external faculty, science board member, and science board fellow at the Santa Fe Institute. Jen was an editor of Physica D: Nonlinearity.

She died on November 12, 2023.
