I am a software systems researcher, working primarily on problems in programming language implementation and scalable runtime systems.  I am deeply interested in developing technology that enables programmers to productively use high-level languages when constructing high performance software systems

I have contributed to a number of technical topics in programming language design and implementation including the analysis and optimization of object-oriented languages, virtual machine design and implementation, scalable runtime systems, Just-In-Time compilation, online feedback-directed optimization, and garbage collection.  

Since joining IBM in 1998, I have worked on a number of projects, including:

  • I am currently helping to bring the Swift programming language to the server as part of the Swift@IBM technical team and the community.
  • I co-lead the X10 Project. X10 is an object-oriented programming language with integrated support for fine-grained concurrency and distribution. Although originally designed for supercomputers, X10 provides scalable performance and programmer productivity on a variety of systems ranging from single multi-core machines, to the cloud, to high-end HPC-style clusters.
  • I was a member of the Metronome Project, which developed the real-time garbage collection technology that became the basis for IBM's WebSphere Real Time product.
  • I am part of the Jikes RVM open source community, serving on the Jikes RVM core team and steering committee. Jikes RVM grew out of the Jalapeño research project at IBM. I worked on the Jalapeño optimizing compiler, adaptive optimization system, and other aspects of the VM runtime.

Many of the software artifacts I use in my research are open source. For more information on my contributions to open source, follow dgrove-oss on GitHub or see my OpenHub page.
