- Elaboration of agglomerated powder prior to thermal spraying using the spray-drying method
- Morphological and micro-structural characterization of powders and deposits: optical microscopy, SEM, FT-IR, thermal analysis, XRD
- Impedance spectroscopy (EIS)
- Mechanical characterization: micro-hardness, interfacial indentation, tensile adhesion, fracture, roughness, profilometry
- Physico-chemical characterization of the ceramic surface properties (surface acidity, point of zero charge, zeta potential, chemical analysis)
- Evaluation of the photocatalytic activities with respect to the degradation of atmospheric and water pollutants

Miscellaneous______________
- Scientific publications in reviewed journals and participations to conferences
- Languages: Romanian-native speaker; French, English- read, spoken, written; German-medium level
