Academia

Teaching

I have contributed to teaching, organizing, and supervising these university courses:

Faculty roles

I have been Ph.D. representative for USI's Faculty of Computer Science in 2018/2019.
During that time, I was the official point of contact between the Faculty and its doctoral students, participating in Faculty meetings and contributing to the strategic decisions of the University.

Awards

  • Awarded a Mobility grant of 18.000 CHF by the Swiss National Science Foundation in 2019.

Community & Open Source

This is a list of my past and current roles as a member of the AI community:

Spektral

I am the main developer of Spektral, an open-source Python library for creating graph neural networks in TensorFlow and Keras. The project has thousands of active users and was one of the first libraries ever created for graph deep learning.
