Kiana Hashemy is an engineer with a PhD in Engineering Seismology from Politecnico di Milano and 5 years of experience in industry in the field of seismic hazard assessment and geotechnical earthquake engineering.

Before joining SEISTER, she was involved in geoconsultancy services working on numerous industrial projects such as oil and gas platforms, industrial plants, artificial islands, highways and railways in Italy and abroad. Her area of expertise covers the field of probabilistic and deterministic seismic hazard assessment, ground motion numerical simulation, site response analysis, liquefaction and stability analysis of soils, signal processing and ground motion record selection and scaling. During her PhD, Kiana was involved in an industrial project defined by a research contract between Politecnico di Milano, Italy and Munich RE, Germany with the objective of seismic hazard and

risk assessment of large urban areas worldwide (Santiago, Chile; Wellington, New Zealand; Thessaloniki, Greece; Istanbul, Turkey etc.) through physics-based ground motion numerical simulations. Her doctoral research was focused specifically on implementation of physics-based numerical approaches for prediction of seismic ground motion in the city of Thessaloniki and broader area which had been selected as a benchmark site in the framework of 2013–2016 STREST FP7 European Collaborative Research Project. For that aim, she performed numerical simulation of seismic wave propagation by constructing a large-scale 3D model of the Thessaloniki broader area based on the available data regarding both the characterization of the seismic sources and geological, geotechnical and geophysical aspects.

Kiana Hashemy
Engineering seismologist

Hussein Shible is a junior engineering seismologist graduated with a civil engineering diploma and achieved his Master and Ph.D. degree in the field of engineering seismology from Grenoble Alpes University in France.

He trained in the research Laboratory of ISTerre (Institut de Science de la Terre, Grenoble, France) and joined CEA-Cadarache during his Ph.D. The Ph.D. work of H. Shible was carried out in the framework of SIGMA-2 program and other research and development programs that concern French nuclear facilities.

His investigations were closely related to site-specific hazard assessments, so he conducted research on topics related to empirical and numerical site effects estimations using different methods. Hussein was involved in an international benchmark (GITEC) on generalized inversion techniques, where he was in charge of coordination of the project and representation in front of the scientific community. He also worked on the development of new ground motion prediction equations for reference hazard conditions, a key point in the hazard assessment studies. He also participated in several different activities such as the preparation of strong-motion databases and geophysical campaigns.


Antoine Poujol


Antoine is a geologist specialized in active tectonics, paleoseismology and quaternary geochronology. He achieved his PhD at Geosciences MONTPELLIER in 2014 with a thesis on the present-day deformation in Morocco along the convergent Africa-Eurasia tectonic plates.

His doctoral research was focused on studying paleo-earthquakes combining field trips and office works (from remote sensing analysis to isotopic geochemistry at lab). After one year working as consultant for seismic hazard companies based in France and Belgium regarding nuclear facilities

projects in Turkey and England, he started a ~4-years postdoctoral position in Taiwan (Asia). During these four years, he performed tectonics and paleoseismological studies on the frontal thrusts of one of the most seismically active area in the world (the Central Range in Taiwan). He performed numerous geological field trips worldwide in order to better understand the active faults and their kinematics as well as their history through the characterization of past earthquake ruptures. Before joining SEISTER, Antoine was working at the University of Tours as Lecturer and Researcher during two years.

Yacine Benjelloun


Yacine is an earthquake geologist with a PhD in Earth Sciences from Grenoble Alpes University (France). He recently joined SEISTER where he contributes on geological site characterization and the development of seismic source models for both probabilistic and deterministic seismic hazard assessments.

Before joining SEISTER, he was involved in carrying out paleoseismic studies along major continental active faults to assess their coseismic and cumulative slip signals and constrain their long-term slip rate and recurrence.

His area of expertise covers geomorphological field investigations, fault trenching and archeoseismology, the acquisition, processing and interpretation of high-resolution topography, general cartography and morphometric analysis performed with GIS, and geochronology. During his PhD, Yacine applied a multidisciplinary approach to characterize the recent activity of the North Anatolian fault in the southeast of the Marmara Sea, in an area with a significant record of damaging historical earthquakes. For this, he combined field work and satellite imagery processing to evaluate the morphological signature of the last major ruptures along the fault. Through an inventory of seismic damage on ancient buildings, he also constrained the EMS-98 intensity range associated with the historical earthquakes.
