About me

I have been always fascinated by science and knowledge. My childhood dream was either to be an astronaut or a scientist. Now, if on the one hand I did not pursuit the first course, and I probably will not play among the stars, on the other hand I feel I am close at achieving the second.

I graduated in 2006 in Physics, with specialty in "theoretical physics" and then I obtained a Ph. D. in "Earth sciences" during which I mainly researched in the field of Applied Geophysics.
The nature of my education, along with the years I spent in the research field, involved a great deal of independent research, requiring initiative, self-motivation, a wide range of technical skills, as well as personal skills, such as team-working, problem-solving, and communicating with people of different scientific background.

Concerning technical skills, I developed the theoretical and practical understanding of many geophysical methods as well as expertise in other scientific disciplines, such as

  • Active Surface waves methods, for example SASW, MASW,
  • Passive surface waves methods, such as SPAC, REMI, ESAC and HVSR (Microseism) 
  • Electrical resistivity tomography
  • Time Domain Electromagnetic method (TEM),
  • Ground Penetrating Radar (GPR)
  • Seismic Reflection and FWI
  • P-waves Tomography
  • Synthetic aperture Radar (SAR)
  • Active contours (image, and data volume segmentation)
  • Segmentation in Medical imaging

 

A deep understanding of the underlying theories allowed me to develop and implement innovative data processing approaches, and to become acquainted with program languages (such as C/C++, Fortran, Basic, Matlab, Bash, TCL/TK, LabVIEW, and recently Python). Indeed, I developed quite few advanced computational programs (e.g. S3DiOpenHVSR, PTomo3D).

I am a fast and accurate writer, with a keen eye for detail and a wide experience on presenting my findings at international conferences. 
I am highly collaborative and good in team working (also remotely), In fact I currently collaborate with both Italian, American and South African research groups.
Further, since some of my open-source programs are being used world-wide ,I am being constantly keep correspondence with researchers many other countries.

I am passionate about teaching and have gone out of my way to create several opportunities to do so despite it not being formally required in any of my research oriented job positions thus far (I even mentored students, at different levels, during the preparation of their graduation exams and co-authored a textbook about Geophysics as part of this endeavor).

 

About my research:
My outmost evolved skill is modeling, data inversion, and algorithm development. I am fascinated by any challenge involving these aspects. Indeed, while most of my career has being spent in Geophysics, I ventured well beyond, investigating topics such as Remote sensing (SAR) and medical imaging. Along the years I cultivated an interdisciplinary perspective of research.

Nevertheless, concerning Geophysics, my interest is toward the enhancement of existing and the design of innovative geophysical approaches. Despite the fact that my work has been mainly focused on near-surface (as reflected by my publications), I have always been fascinated by the exploration geophysics as applied to both oil and mines, and did my best to acquire knowledge on this topic as well.
 
My current projects concern:

  • Development of a 3-D subsurface characterization method to infer the shallow elastic properties, especially using a limited number of receivers and sparse arrays. This has direct applications in complex subsurface environments such as landslides, excavations and building foundations. It is one of my goals to continue this research, possibly by finding private sponsors.
  • As formerly part of a research group that manages a seismometers net to monitor a geothermal site to detect any induced seismicity. I am developing a large scale 3-D elastic subsurface model, to be used for seismic sources localization and simulation of seismic disaster scenarios. I am looking forward to apply the methods of this research to other sites as well.
  • I recently published two different software ("OpenHVSR-Inversion" and ("OpenHVSR-Processing -Toolkit") for the signal-processing, modeling and inversion of massive HVSR data-sets. An analogous for TEM data is currently under development. It is one of my research goals to promote their use and further development.
  • During my recent experience with Georgia Institute of Technology I had the opportunity to combine Geophysical methods with geometric PDE methods for data processing (known as active surfaces and level set method). This is a very promising research that only recently entered the Geophysics scenario. Its full potential only waits to be explored.
  • Development of algorithms for radar with focus on imaging and shape reconstruction. These techniques may find application in autonomous automotive, space, and defense systems.

 

Research I would like to pursuit:

Well… how much time do you have?
