CV

Profile

Detector electronics engineer with more than 10 years of experience in instrumentation for free-electron laser and accelerator facilities, with hands-on work on X-ray detectors and sensors (DEPFET, LGAD). I take detector and instrument electronics from requirements through design, integration and commissioning to safe operation.

Work package leader for electronics development in detector development projects at European XFEL. Appointed VEFK for the detector laboratories. Executive PhD candidate in Engineering Physics and Materials at Ca’ Foscari University of Venice, working on test instrumentation and AI-assisted model-based systems engineering for X-ray detectors.
