Research Engineer: Dr. Rocco Crescenzi

Rocco Crescenzi received the degree in Aerospace Engineering at the ”Sapienza” University of Rome in 2002 and successively the Doctorate degree in Industrial Production Engineering. He works as mechanical engineer at the Nanostructure Laboratory in the Department of Information Engineering, Electronics and Telecommunication at ”Sapienza” University of Rome. He is employed in the Electronic Technological Laboratory as expert in plasma process (RIE, Sputtering and PECVD), thermal vapor deposition, photolithographic process, wet etching and electrochemical processes. His researches focus on the MEMS and his research group has developed several experimental setups for the mechanical characterization of the micro and nanostructured materials. His designing interests regard the finite element modeling, in particular the modeling of micro-electromechanical-system (MEMS). He supports the MEMS course at the same University since 2004.
Research Associate: Dr. Vittorio Cecconi

Vittorio is a researcher (RTDA) at Sapienza University of Rome (Italy). His research career has consistently focused on complex photonics, beginning with his master’s thesis in physics at Sapienza on the nonlinear propagation of optical vortices in nonlocal media. He then pursued his PhD in Physics at the University of Sussex, where he developed expertise in THz hyperspectral imaging and scattering-assisted wavefront control in complex media. Following his doctorate, he held a Vice-Chancellor Independent Research Fellowship and the C-DICE Fellowship at Loughborough University (UK), before returning to Sapienza in August 2025. At Sapienza, he is exploring hollow-core fibres for endoscopic imaging and tumour treatment within the EIC Pathfinder Open project MULTISCOPE.
