Biography

Paris Smaragdis completed his masters (1997), Ph.D. (2001), and postdoctoral studies (2002) at MIT, performing research on computational audition. Prior to the University of Illinois he was a research scientist at MERL, and Adobe Research. His research is focused on machine learning approaches to solving various audio signal processing problems. In 2006 he was selected by MIT’s Technology Review as one of the year’s top young technology innovators (TR35) for his work on machine listening, he has won the IEEE Signal Processing Society Best Paper Award twice (2017 and 2020), he was elected an IEEE Fellow (class of 2015), and selected as an IEEE Signal Processing Society Distinguished Lecturer (2016-2017).

He has served in the IEEE Signal Processing Society Board of Governors (2017-2020), as chair of the Machine Learning for Signal Processing Technical Committee of the IEEE (2012-2014), as chair of the Audio and Acoustics Signal Processing Technical Committee of the IEEE (2018-2020), as chair of the IEEE SPS Data Science Initiative (2019-2020), and as chair of the Audio and Acoustics Signal Processing Technical Committee of the IEEE, and from 2012 to 2015 he chaired the steering committee of the international community on Latent Variable Analysis and Source Separation (2012-2015).

He is currently the Editor in Chief for the ACM/IEEE Transactions on Audio, Speech, and Language Processing. He has been a Senior Area Editor for IEEE’s Signal Processing Transactions and IEEE’s Open Journal of Signal Processing. His research has been productized multiple times in commercial software that is in use by millions of users worldwide, and he holds more than 40 US patents, as well as patents in Japan and Europe. He has been an active consultant on audio technologies with multiple Fortune 500 companies.

Research Statement

Paris Smaragdis is best known for contributions in the field of audio processing, more specifically on the problem of source separation (the process of extracting an isolated signal from a mixture). His work on Frequency Domain Independent Component Analysis resulted in the first practical real-time implementations of such systems in the 90s. His later work on Non-Negative Spectral Factorizations was widely adopted for many audio applications, and more recently his introduction of end-to-end deep learning methods for source separation and denoising has resulted in wide adoption.

Smaragdis’ current research focus is on very efficient on-device processing of audio using deep learning, as well as methods for distributed learning over thousands of sensors. He is currently investigating the use of graph models for parameter-free representations of time sequences, binary network signal processing systems, online on-device learning, and is also interested in fully-differentiable digital signal processing systems.
