Grant

Chen, an assistant professor of computer science at Pomona
College, has been awarded a National Science Foundation
Career Grant of $400,000. The grant, which will be
distributed over five years, will fund a project on
“Preconditioning Large, Sparse Linear Systems: Theory and
Practice."
The National Science Foundation's Career grant is its most
prestigious award supporting the early career-development
activities of those teacher-scholars who are most likely to
become the academic leaders of the 21st century. Awardees
are selected on the basis of creative proposals that
effectively integrate research and education.
Chen focuses her research primarily on sparse matrix
algorithms though her interests also include parallel
computing, graph theory, numerical linear algebra and
scientific computing. The funded project focuses on
preconditioners, which are methods for solving large linear
algebra problems more quickly and accurately. The goal of
this project is the development of better preconditioners,
as well as tools to help users choose preconditioners that
are likely to be beneficial for their particular problem.
The initial focus will be on preconditioners that are based
on reordering the rows and/or columns of a matrix and those
that compute an incomplete factorization of the matrix.
Chen plans to involve up to four students per year in the
research. In addition to reaching out to groups
traditionally underrepresented in computer science, she also
plans to develop and refine courses that emphasize the role
of mathematics in computer science, as well as of courses
that give a basic understanding of computing to students who
are not computer science majors but whose education will
nevertheless be enhanced by such knowledge.
A member of the Pomona College faculty since 2002, Chen
teaches Introduction to Computer Science, Algorithms,
Discrete Mathematics and Parallel Computing. She earned her
Ph.D. from the University of California, Berkeley.
Pomona College is one of the nation’s premier liberal arts
institutions, offering a comprehensive program in the arts,
humanities, social sciences and natural sciences. Its
hallmarks include small classes, close relationships between
students and faculty, and a range of opportunities for
student research. Visit Pomona College on the web at
