Personal profile

Research interests

My research is in the area of logic and proof theory, and has focused on canonical graphical representations of proof, commonly known as proof nets.

Fingerprint Fingerprint is based on mining the text of the person's scientific documents to create an index of weighted terms, which defines the key subjects of each individual researcher.
