3. Research Interests and Experience

Physics of the Solid Earth and Applied Geophysics: Main fields of interest are the geophysical applications of Electromagnetism and associated theory, the physics of the earthquake source, the statistical physics of seismicity and the analysis of tectonically/ seismically active tectonic domains. More specifically, my research has focused on:

Ø  Digital time series and image processing and analysis: Theory and application of series/image decompositions, filters, time domain systems and high resolution spectral analysis techniques.

Ø  Geophysical applications of Electromagnetism: Experimental investigation of the EarthIonosphere cavity resonances (Schumann resonances) and their applicability to electromagnetic earth sounding; Magnetotelluric theory; Electrodynamics of the solid Earthwave propagation and diffusion in non-uniform or complex media; Electromagnetic sounding and detection of buried structures; Algorithm and software development.

Ø  Ground Penetrating Radar: Development of novel, advanced data processing methods; development of advanced software for integrated processing, modelling, visualization and interpretation of single-offset GPR data (matGPR software).

Ø  Physics of the Earthquake Source and the Statistics of Earthquakes: Spontaneous electrification of stressed rocks and associated electric and electromagnetic effects; Statistical Physics of seismicity/ seismogenesis and the earthquake cycle – non-linear effects in seismicity and the seismic cycle; Statistical Seismology; Earthquake Hazard Analysis with emphasis on the local and topographic effects on ground motion.

Ø  Geologically Applied Geophysics: Analysis of Earth structure, active tectonics and crustal deformation with joint application of Magnetotelluric, Seismotectonic, Potential Field, Geodetic, Geological and advanced image analysis and decomposition methods.

Ø  Scientific Programming mainly with FORTRAN, C and MATLAB.

5. Computer Software

1.      matGPR: The Ground Probing Radar (GPR) has become an invaluable means of exploring shallow structures for geoscientific, engineering environmental and archaeological work. At the same time, GPR analysis software is mostly proprietary and expensive. The academic freeware community has been slow to react and the limited free software is usually highly focused on specific problems and generally unorganized. The current version, matGPR Release 3.5, is the product of a continued effort to produce a cross-platform freeware analysis and interpretation package, which can also be expandable and customizable to the requirements of a particular user with relatively little programming effort. matGPR was realized with MATLAB™, an ideal platform for the development of such software as it offers a complete programming environment and solutions for the development of advanced analysis software. The result is a GUI-driven, user friendly program providing a quite broad and functional range of tools for the analysis and visualization of zero and single-offset GPR data collected with several different types of instruments. matGPR is available free of charge for research and education; click here for more details and downloading instructions. At this point in time, there are hundreds of known matGPR users worldwide; anonymous statistical data is available at http://www.motigo.com/en_US/webstats/catalog/a/b/4808192.

2.      maTEM: Software system, written in MATLAB, to interpret TEM sounding data. The program, is designed to process, model and invert multiple soundings, either individually, or simultaneously along profiles. The latter capability allows for laterally constrained inversion, so as to generate pseudo-2D or 2D resistivity sections based on the program EM1DINV v2.13 by the Hydro-Geophysics Group of the University of Aarhus, Denmark. The user may import, display, denoise and smooth multiple sounding data, perform approximate inversions, design 1-D model(s) graphically, perform forward modelling and inversion, generate/ update a data base to store the results and use the data base to create 2-D and 3-D displays of the geoelectric structure with built-in graphical functions. maTEM is highly modular so that additional functions can be added at any time, at minimal programming cost. maTEM is fully functional but not fully debugged and is not yet freely available for downloading. Nevertheless, it may be provided to interested colleagues upon request, subject to the applicant having secured a license to use em1dinv from its own authors; for an application to use em1dinv please click here.
