Elias Zea Marcano

I am an assistant professor of engineering acoustics at The Marcus Wallenberg Laboratory for Sound and Vibration Research (MWL). My research interests span from theoretical to experimental methods, with a strong focus on sparse signal processing, harmonic analysis, and data-driven methods.

I am a reviewer in several international journals of acoustics, vibrations, and signal processing: The Journal of the Acoustical Society of America; Journal of Sound and Vibration; Applied Acoustics; EURASIP Journal on Audio, Speech, and Music Processing; Mechanical Systems and Signal Processing; IEEE Signal Processing Letters, Acta Acustica; Noise Control and Engineering Journal; Journal of Low Frequency Noise, Vibration and Active Control. I am a Guest Editor in the Journal of Theoretical and Computational Acoustics.
