What we work on

Research themes

All research areas

Learning with graphs

Graph neural networks, temporal and higher-order graph analytics, topological signal processing, and conformal inference.

SP for communications

Integrated sensing and communications, reconfigurable intelligent surfaces, near-field and distributed systems, and AI/ML for wireless.

Decentralized learning

Federated and decentralized optimization with constraints, non-IID data, privacy guarantees, and limited communication.

Sparse sensing

Sensor selection and placement, sparse arrays, and graph sampling: acquiring only the data that inference actually needs.
