Research Description

Improving the performance of programs for a wide range of systems (from resource-constrained devices to clusters of workstations) via adaptive compiler and runtime techniques that are guided by dynamically changing program behavior and resource availability.

Research Groups

• RACELab -- the UCSB Lab for Research on Adaptive Compilation Envionments

Biography

Chandra Krintz is an Associate Professor at the University of California, Santa Barbara (UCSB). Chandra's research interests include automatic and adaptive compiler, programming language, virtual runtime, and operating system techniques that improve performance (for high-end systems) and that increase battery life (for mobile, resource-constrained devices). In particular, her work focuses on exploiting repeating patterns in the time- varying behavior of underlying resources, applications, and workloads to guide dynamic optimization and specialization of program and system components. Chandra has supervised and mentored over 30 students, has published her work in a wide range of ACM venues including CGO, ECOOP, PACT, PLDI, OOPSLA, ASPLOS, and others, and leads several educational and outreach programs that introduce computer science to young people, particularly those from underrepresented groups. Chandra's efforts have been recognized with a 2006 NSF CAREER award, a 2008 co-award as Outstanding Faculty Member in Computer Science for exceptional teaching contributions, and the 2008 CRA-W Anita Borg Early Career Award (BECA). Chandra has served her community by participating as a member of a number of technical program committees, as technical program chair (PPPJ'06), as general conference chair (VEE'07), workshop co-chair (2008 Workshop on Programming Language Curriculum), and as the elected Vice Chair of the Executive Committee of the ACM Special Interest Group for Programming Languages (SIGPLAN) which oversees the organization of the conference venues and programs in her research area.
