Research interests

Quantum information science with photons on a chip.

I'm interested in fundamental and technological aspects of quantum information and my research goal is the development and test of photonics circuits for quantum computing which ultimately will be the building blocks of a quantum computer. The innovative part of my research is the use of integrated waveguides to miniaturise the circuits.
I also particularly enjoy working with several collaborators worldwide on multidisciplinary projects bringing together physics, biology and chemistry.
