I'm currently a Researcher at the Seismological Division of the Geological Survey of Israel (GSI). I focus on real-time seismology and Earthquake Early Warning Systems (EEWS) and on maintaining, monitoring and improving the current national Israel Seismic Network (ISN). I'm also interested in enhancing the seismic network by incorporating low-cost MEMS accelerometer systems.
In addition to Earthquake Seismology, I also specialize in Geodesy, in particular, processing InSAR data to study natural hazards and active tectonics processes and to address geodynamical and geophysical problems, such as the sinkholes, lithosphere response to the receding Dead Sea, current fault activity etc.
I use various InSAR techniques including: InSAR stacking, PSInSAR or IPTA and Modeling Inversion. During my professional training, I have acquired valuable geophysical tools for processing a wide range of geophysical data: seismological, geological and geodetic, in order to address topics in natural hazards, tectonics, geodynamics, earth structure and more. My practical experience includes developing methods and tools to efficiently process large amounts of data, monitoring and creating automated processing systems to help mitigate natural hazards.

During my Postdoc, at the Berkeley Seismology Laboratory (BSL) at the University of California Berkeley (UCB). I worked on adapting BSL's ElarmS EEWS to Israel and other places in the world. I was also developing low-cost MEMS acceleromers systems.

Working as a researcher, at Tel-Aviv University (TAU), I worked at the DeadSeaNet seismic observatory at the department of Geophysics, Atmospheric and Planetary Sciences. This trans-border seismic observatory consists of a cluster of seismic arrays of different types, deployed in the Dead Sea region as well as control facilities hosted at TAU, based on SeisComP3. I focused on the development of various algorithms for SeisComP3 and on local microseismicity databases. I also managed and maintained the Seiscomp3 servers.

On my previous InSAR works I used stacking and PSInSAR to study the ongoing deformations along the Carmel Fault, Israel. I have used basic InSAR techniques to explore the proposed course of the Dead-Red Conduit, Israel and to isolate course of events of dike injection and earthquake swarm around Oldoinyo Lengai carbonatitic volcano, Tanzania.

During my PhD. study, I focused on the influence of the ongoing Dead-Sea (Israel) water-level drop on the lithosphere and on sinkhole development along its shores.
Using a specifically tailored time-series analysis and elastic modeling a regional uplift response of the crust was observed. On a local scale, sinkholes precursory subsidence was detected by integrating InSAR and LiDAR high-resolution measurements.
