Rockstar🎓
Top SchoolJonathan Le Roux is a distinguished research scientist at MERL with nine years of experience leading speech and audio research, currently focused on machine learning for speech enhancement and source separation. He blends deep academic roots in audio signal processing—spanning Ph.D. and postdoc work on F0 estimation, spectrogram-aware reconstruction, and model-based source separation—with practical leadership of the Speech & Audio team. Jonathan’s expertise bridges model-based and deep-learning approaches, covering the full speech pipeline from acoustic and language modeling to dialog systems and user prediction. Known for inventive extensions to NMF and harmonically-constrained GMMs, he brings a rare combination of statistical inference rigor and hands-on machine-listening practice. Based in Cambridge, MA, he pairs a strong mathematical background with a track record of shipping advanced algorithms from research prototypes toward real-world systems.
