报告摘要

　　In this presentation, I will highlight my research contributions in semiconductor detector development, charged-particle tracking, and heavy-flavor physics within large-scale high-energy physics experiments. My work includes the characterization of diamond detectors and next-generation monolithic active pixel sensors (MAPS) developed for the ALICE ITS3 upgrade, based on detailed laboratory measurements and test-beam studies of spatial resolution, timing performance, and detection efficiency. I have also made significant contributions to the development of tracking algorithms and fast simulation tools for the ALICE, ALICE3, and ePIC detectors. On the physics side, I will present recent Run 3 results already approved from the ALICE experiment on charm-hadron correlations obtained using machine-learning techniques, which provide new insights into heavy-quark fragmentation and hadronisation mechanisms. Finally, I will discuss my ongoing and future research plans, focusing on heavy-flavor measurements at the LHC and the Electron–Ion Collider, combining advanced detector technologies with precision tracking and data analysis.
