Summary
👤
Senior🎓
Top SchoolJonathan Clark is a research scientist with 15 years of experience specializing in multilingual machine learning and neural machine translation, currently working on multilinguality for Google's Gemini. He previously led core translation efforts at Microsoft Translator and built production training infrastructure at Safaba (now part of Amazon), shipping features that powered Bing, Skype, and custom translator services. A Carnegie Mellon PhD in Language Technologies, he combines deep academic grounding with hands-on systems and performance engineering—evidenced by contributions to high-profile open-source projects like Moses and KenLM. His work spans model research, optimization, and reliable deployment, with a knack for squeezing performance and observability out of language-model pipelines. Based in the Greater Seattle Area, he keeps active in open-source artifacts from his grad-school era while driving industry-scale multilingual systems. Colleagues describe him as someone who bridges research rigor and production practicality, often surfacing subtle engineering gains such as precise timing and memory-use estimates that improve real-world translation workflows.

Moses, the machine translation system
Role in this project:Back-end Developer
Back-end DeveloperContributions:9 commits in 4 months
Contributions summary:Jonathan's contributions focused on enhancing the Moses machine translation system. They modified the code to include phrase segmentation information in the n-best list output, improving the reporting of translation results. The changes involved modifying `IOWrapper.cpp` and `Main.cpp` to incorporate this new functionality. They also updated the timer class for more precise timing on systems supporting `CLOCK_MONOTONIC`.
