Research Scientist at Microsoft · ML Systems

Thamme “TG” Gowda

I build AI systems that survive the trip from research to production.

My work spans multilingual and multimodal models, data and distributed training, evaluation, quantization, GPU kernels, and low-latency inference.

WMT Model Compression and TahomaMT

I lead the WMT Model Compression shared task and built its two-year evaluation infrastructure for runnable systems, controlled H100 execution, and quality–footprint–speed trade-offs. TahomaMT tests those ideas in a custom C++/CUDA runtime.

Multilingual data and training

MTData, RTG, NLCodec, and Many-to-English

I built an open toolchain for reproducible MT data, vocabularies, training, and inference, then used it to train a single model spanning more than 500 source languages. As a WMT General MT organizer from 2022 through 2026, I have maintained versioned MTData recipes that give participants reproducible constrained-track datasets across five editions.

A practical web interface, REST API, and batch decoder for deploying Meta's No Language Left Behind models across 200 languages. It remains my most widely adopted personal repository.

Sparkler

I created Sparkler at USC: an extensible web crawler built around Apache Spark, Kafka, Solr/Lucene, Tika, and distributed JavaScript rendering. I later handed the project to its maintainers when I shifted focus to my Ph.D.

Background

Research depth, engineering range.

At Microsoft, I work on multilingual and multimodal AI and the systems that train and serve these models. I have also helped organize the WMT General MT shared task for five consecutive editions, from 2022 through 2026. Previously, I spent five years as a Research Engineer at USC ISI and worked as a Data Scientist intern at NASA JPL.

I earned my Ph.D. and M.S. in Computer Science from USC. My doctoral work studied rare phenomena learning in neural machine translation (dissertation). I have also built software at startups, co-founded Datoin, and served as an Apache Software Foundation committer and PMC member.

Beyond the work

I grew up in a farming family in southern India, where work was measured in acres and yield, not hours. That upbringing still shapes how I approach hard problems: understand the whole system, stay practical, and judge the work by what it produces.
