Industrial Experience

1999-2001- Geotechnical Acting Chief. Tractebel Consulting Engineering, Romanian Branch.

During this period I performed the following activities:

-Geotechnical laboratory analysis for soils;

-Design of foundations for buildings, roads and railways;

-Design of retaining structures for the stabilization of slopes, embankments and cuttings;

-Stability computation for dams.

For the field geotechnical investigation I use the HYSON 100 kN LW static penetrometer manufactured by a.p.v.d.Berg –Holland. With this equipment is possible to record four independent parameters (cone tip resistance, mantle friction, pore water pressure and inclination of the well). There is also the possibility to take sample of soil from a certain depth in order to perform laboratory analysis.

1998-1999 Acting Chief Geophysicist –“The Great Man Made River” Project. I.N.C. Il Nuovo Castoro Libyan Branch, Libya.

1997-1998 Junior Geophysicist –“The Great Man Made River” Project. I.N.C. Il Nuovo Castoro Libyan Branch, Libya.

Between 1997 and 1999 I worked in Libya in Al-Saunah water field within the geophysical department. The following methods were performed:

-Electrical Log (long and short normal)-Natural Gamma

-Three arm caliper

-Four arm caliper

-Cement bond log

-Temperature/Conductivity Log

-Dual Neutron Log

-Gamma-Gamma Log

-Video Inspection (CCTV Survey).

I have experience in interpretation and processing data using geophysical software (e.q. WELLCAD, LOGCAD).

I performed the calibration tests into two test-wells every month for the radioactive methods and verifications for all the tools. I also performed the regular maintenance and repairing for all the geophysical equipment. The equipment was provided by Robertson Geologging LTD - U.K.

Research Interests

My recent research interests comprise a broad area in geophysics: computational geodynamics, oceanic plate mechanics, magnetism and gravity, volcanism, metamorphic processes in subduction zone and crust deformation monitoring.

In the area of computational geodynamics I have been working in the development of 2-D and 3-D numerical models of tectonic processes related with various subduction zones along the “Ring of Fire” (Mexico, Guatemala, Kamchatka and recently Chile). The main goal of my current work is to provide a basis for the sound interpretation of seismological observations made on local, regional, and global scales. From these models I hope to understand better how plate tectonics works, how plate tectonics and mantle flow are related, how and why mantle convection evolves over long time periods.

The state of stress in subduction slabs and its relationship with the intraslab earthquakes is another scientific interest that I have. I developed 2D numerical schemes to compute a type of stresses inside the subducting slabs which has been neglected in the last decades. It is about the thermally induced stresses in oceanic plates due to non-uniform heating during subduction. With these studies I hope to comprehend why the intraslab earthquakes occur between certain depths and what is the magnitude of the deviatoric stress field which might produce such earthquakes.

Additionally, I am involved in studies related with flexural deformation of lithosphere at fracture zones, gravity anomalies and lithospheric flexure.

Furthermore, my research interests are related with the application of gravity and magnetic anomalies to understand tectonic problems related with subduction zones. Actually I used these anomalies to constrain the subduction zones geometry, to study the sediment accumulation at the deep oceanic trenches and to study the mantle wedge metamorphism (i.e serpentinization).

Another important part of my research is related with the volcanism caused by subduction. I have been studying the propagation of magma through a convective mantle wedge using numerical models. Such models give new constraints regarding the magma viscosity and temperature inside the mantle beneath volcanic arcs. Also, I study the ascent time of molten magma blobs through the mantle and the relation with the U-Th disequilibria. Recently I begin to study the lahars behavior in active volcanoes.

The metamorphic processes in subducting slabs represent other scientific interest that I have. I investigate the slab dehydration and its relationship with the recently discovered “slow earthquakes”. Such studies can provide new insights regarding the actual mechanism that produces the slow earthquakes.

Finally, one of my central scientific interests is represented by field measurements. Using GPS and tiltmeter measurements I have been studying in the last four years deformation processes related with subduction zones and plate boundaries. The main outcome from such investigations is the better understanding of the seismic cycle and plate boundary forces.
