My current and past research activities

Wireless devices and privacy

More and more objects are equipped with wireless communications interfaces. The radio signal emitted by those devices can be easily collected and, in some cases, used to obtain private information about the owner.

Erasure correcting codes

Erasure correcting codes are a solution to make data transmissions resilient to packet loss. LDPC (low-density parity check) codes offer good erasure correction capabilities with a low en/decoding complexity.
