Robert Deline is a Sr Principal Researcher at Microsoft with nearly three decades of industry and academic experience and nine years focused on research-driven engineering practice. He invents developer-facing tools and interactive environments—projects like "Glinda," "Tempe," and "Logan"—to boost productivity, reduce errors, and make machine learning and streaming telemetry more approachable and reliable. A Carnegie Mellon PhD and former University of Washington affiliate professor, he blends formal software-engineering rigor with practical systems work, from model training for IoT to real-time query engines. His open-source contributions include meaningful backend and ML engineering work on Microsoft's Embedded Learning Library (ELL), where he improved bindings, packaging, and long-lived scripting robustness. Colleagues know him for turning careful empirical studies of the emerging data-science profession into usable tooling that addresses day-to-day developer pain points.

Contributions summary:Robert significantly contributed to the Embedded Learning Library (ELL) by implementing parameter validation for the SWIG interface, enhancing the robustness of the Python and JavaScript bindings. They developed a Python conda package for ELL, integrating build outputs and necessary utility files. Furthermore, the user fixed an IR emitter bug, ensuring correct identifier generation in long-lived scripting sessions. They also revived and enhanced the `ell_module` to support the ELLView, adding new SWIG methods for loading maps and model refinement.
A Typescript library for parsing Python 3 and doing basic program analysis, like forming control-flow graphs and def-use chains.
