Working on Continual Learning and Graph Representation Learning. I carried on foundational research on novel learning algorithms and neural architectures, investigating agents capable of processing and learning from continuous streams of data, mostly within dynamic visual environments. Developing open‑source libraries for training and inference in Graph Neural Networks. Published at NeurIPS, AAAI, IJCAI, TPAMI, TNNLS. Reviewer in machine learning venues (NeurIPS, ICML, ICLR, etc.) and journals (TPAMI, TNNLS, Artificial Intelligence etc.)
