Areas of Interest and Research

Zahra is interested in multidisciplinary research in seismological signal processing. Within her Ph.D. project ( "Volcanic tremor analysis based on advanced signal processing concepts including music information retrieval (MIR) strategies"), she is trying to exploit MIR techniques beyond music.  Inspired by the algorithms for separating harmonic and percussive components in musical signal processing, she developed a method to extract volcanic tremor signals from seismic recordings (Zali et al., 2021). The overall goal behind this work  is to get more insights into eruptive processes using the extracted volcanic tremor signal.

In addition,  in the field of signal decomposition she is working on algorithms for noise reduction in ocean-bottom seismometer (OBS) recordings.
