Biography

Dr. Daniel Chavarría-Miranda is a Senior Research Scientist and the Team Leader of High Performance Computing at PNNL. Chavarría is currently participating in the Department of Energy Office of Science Center for Technology for Advanced Scientific Component Software (TASCS). He also is involved in the DOE ASCR Center for Scalable Parallel Programming Models (PModels2).

Chavarría-Miranda also serves as co-PI for a DoD-funded Center for Adaptive Supercomputing Software-Multithreaded Architectures (CASS-MT), with a focus on scalable highly irregular applications and systems software. He has also served as the Principal Investigator for several PNNL-funded Laboratory Directed Research & Development projects in the application of reconfigurable and hybrid systems to scientific codes. He also has been a collaborator in PNNL-funded LDRD projects in the application of multithreaded systems to non-traditional scientific applications.

Chavarría-Miranda received his M.S./Ph.D. in Computer Science from Rice University in 2004. As part of his doctoral training, Chavarría-Miranda participated in designing and developing key portions of Rice University's dHPF research compiler.
