Currently, Eugeniu is employed as a Research Fellow in the ARC Centre of Excellence in Advanced Molecular Imaging (AMI). His role is mainly to manage the Nanofabrication node within the Centre. The main goals of the group are: development of bio-platforms for sample delivery for X-Ray Free Electron Lasers, development of microfluidics for cell trapping and diagnostics, and fabrication of plasmonic devices for molecular sensing.

In his previous position, Eugeniu was employed as a Research Fellow in the ARC Centre of Excellence for Coherent X-ray Science (CXS). His role was mainly to provide his colleagues with test samples and samples of interest, so they can assess the degree of certainty of specific set of experiments and methods, which is of high importance for providing high degree of research and scientific output. This also involved the development of new fabrication methods and characterization of various samples. Within his role, he was interested in development of new generation of high-efficiency Fresnel Zone Plate for X-Ray optics.

Eugeniu completed a Ph.D. in Materials Science and Engineering (2007) at Friedrich-Alexander-Universitat Erlangen-Nurnberg (Germany). His doctoral thesis "Organically-modified semiconductor surfaces: from electron-beam induced modification to wettability control" involved the investigation of a new class of materials (self-assembled monolayers) on semiconductor surfaces. This is a novel area where organic molecules are adsorbed to semiconductor surfaces. He has studied the possibility of patterning such surfaces by means of electrons and metallization. Additionally, he has explored the possibility of modifying titanium oxide surface characteristics by various methods: chemical functionalization and geometrical alteration of titanium oxide surface, and UV-light induced modification of its wetting properties.
