2004- present Doctoral programme subject: “Thin Organic films on silicon support”, at Organic Department, Bucharest University

Professional experience:

Investigation of the influence of electrochemical etching parameters on silicon and on its morphology, composition, and structure
Fabrication and investigation of the bioresorbable mesoporous silicon like an implant for controlled drug delivery - the characterization of the impregnation process of the “reservoir” with different microelements (metals) as: Fe, Mg, K, Ag, Au in a variety of preparation conditions; SEM, EDX, atomic absorption spectroscopy (AAS) measurements.
Due to the modification of PS properties in time, different physico-chemical methods were developed for surface modification according with subsequent applications: stabilisation for integration in an optoelectronic device at the beginning, and recently functionalisation for achieving of nanostructured materials biocompatibilities for interfaces with biological systems.
the cell culture growth on the surface of the micro/mezo porous silicon. Microscopic and spectroscopic methods (SEM, fluorescence microscopy and spectroscopy) were used for characterization of the adherence processes and the interactions of live cells with biomaterial.
The study of DNA infiltration in the Si pores after exposure of the derivatized PS surfaces in a solution of protein or DNA strand
Fabrication and investigation of the bioresorbable mesoporous silicon like an implant for controlled drug delivery - the characterization of the impregnation process of the “reservoir”
