Rafael Andres Herrera Guaitero is a Ph.D. candidate in the Department of Electrical and Computer Engineering at the University of Delaware in the US. His research interests lie at the intersection of High-Performance Computing, Runtime Systems, and Compilers, with a strong focus on making programs run faster, and utilize resources efficiently on current and future computing architectures. With a bachelor's degree in electronic engineering from the Pontificia Universidad Javeriana in Colombia, Rafael is currently a Research Assistant at the Computer Architecture and Parallel Systems Laboratory (CAPSL) at the University of Delaware. Here, he actively works on the Codelet Model domain-specific language extension and intermediate representation, known as CODIR, which contributes to the definition of a common abstraction for parallel systems, promoting software modularity and portability across various architectures. Rafael's passion lies in exploring different programming models for many-core and heterogeneous architectures, particularly from the compiler's perspective, and CODIR represents a significant step forward in addressing this intricate challenge. His ultimate goal is to advance the field of High-Performance Computing and parallel programming models to enhance program execution on modern and emerging parallel systems.
